Black Bullhead

Ameiurus (Genus) – Bullhead Catfishes

Scientific Name:              Ameiurus (Genus); Ameiurus melas, Ameiurus natalis

Common Name(s):          Bullhead Catfish; Black Bullhead, Yellow Bullhead
Creek Cats, Mud Cats, Yellow Cats, Black Cats, Polliwogs

Identification:

There are seven species of bullhead catfishes, all native to North America and all within the genus Ameiurus. There are two common species of bullheads in Northwest Arkansas, the black and yellow.  The black bullhead Ameiurus melas has dark whiskers, called barbles, under its chin that are either gray or black and which differ from the white ones of the yellow bullhead Ameiurus natalis. Both black and yellow bullheads are solid brownish-yellow fading to white on their bellies. All bullhead catfishes have a quadrate, unforked tail fin which distinguishes them from other catfish species. They also have spines in the dorsal fin on their backs and both pectoral fins on their sides. Like all catfish, the bullheads have an adipose fin, a small fleshy projection on their back just in front of their tail fin. Bullheads are commonly 12-16 inches and weigh 1-2 lbs.

Range:

The range for Bullheads differs slightly but are consistently found east of Wyoming and Colorado. Black bullheads can be found in parts of southern Canada, south to Texas, and in the central United States.  Yellow bullheads are found from the central to the eastern United States. In Arkansas, black and yellow bullheads are found state-wide in appropriate habitats.

Ecology:

Bullheads are warm water fish, preferring water temperatures around 75-85°F. They are considered “rough fish” as opposed to “game fish” in part because they are seldom sought after and few regulations govern their harvest. The meat is of good quality especially when caught from clean waters and has even been described as having a sweet flavor. Small size is typically the reason more bullheads are not harvested.

Bullheads are generally not stocked intentionally. They tend to overpopulate in small impoundments.  Their feeding activity can create muddy conditions impact water quality. Bullheads are very tolerant of these conditions, but many gamefish are not. There have been accidental stockings by misidentifying them with other catfish species. This has resulted in established populations well outside of their native ranges.

Spawning in Arkansas occurs from May-June when temperatures range from 66-75°F. Females primarily make oval shaped nests in shallower water, although occasionally males will help construct nests. Both parents guard the nest until young hatch. Young then school with the parents until they are around 1 inch long when the parents abandon them. Bullheads are thought to be monogamous.

Bullheads are bottom feeders and consume almost anything, including fish, insects, crayfish, and dead organisms. Like other catfish, they rely on their olfactory senses to find food instead of their eyesight, which is performed using their mouth barbles. Yellow bullheads are the pickiest out of the two species.  All bullheads primarily feed at night.

Special Notes:

Here in Bella Vista, bullheads are not stocked deliberately in any of the lakes. They are commonly found in golf course ponds due to periodic inundation by Little Sugar Creek which maintains good populations of both species. Populations in our lakes remain low due to predation by game fish, primarily largemouth bass. It is probable that they are found in all our lakes, as they were a native stream fish before the valleys were flooded.

Species Profile – Lontra canadensis – River Otter

Scientific Name: Carya (Genus)
Common Name(s): River Otter, North American River Otter

Identification:
River otters live in and around water. They have long streamlined bodies with a long, tapered tail. Otters have oily brown fur all over their body, including their tail; this can help distinguish them from the beaver with its hairless tail. The fur on their underside is typically a lighter brown or gray. Otters also have long prominent whiskers. Their feet are webbed, and their hands are very dexterous. Otters weigh 10-30 lbs., with males larger than females, and are 24-42 inches in length.

Range:
Otters were natively found throughout North America, from Alaska and Canada to the Gulf of Mexico, and from coast-to-coast. However, habitat destruction, urbanization, and pollution have extirpated the river otter from some states in the U.S.

Ecology:
River otters inhabit more than just rivers. They can be found in inland freshwaters, such as rivers and lakes, and in marine and brackish waters. They prefer waters with adjacent woodlands but can survive in any location with a steady supply of food and access to a waterbody. Otters live in dens built in a natural hollow, an undercut riverbank, hollow log, or in the burrows of other animals. The entrance may be under water or above ground. The den is typically lined with leaves, grass, bark, and moss.

Otters are typically ambush predators, lunging and grabbing prey, rather than pursuing prey. They are well adapted for hunting in water: they can stay submerged for up to 4 minutes, swim at a speed of nearly 7 mph, and dive to a depth of 65 ft. While their primary diet is fish and crayfish, they will opportunistically eat anything, including fruit, reptiles, amphibians, birds, insects, and small mammals. They will avoid carrion.

Reproduction is viable at two years of age, and males usually mate with multiple females. Breeding occurs from December to April. While gestation lasts two months, otters delay implantation for up to eight months, meaning that birth usually occurs 10-12 months after copulation. Litters usually consist of one to three pups, rarely up to five. Pups are born fully furred but are blind and toothless. They open their eyes at four weeks, consume solid food at nine weeks, wean at 12 weeks, and are provided food up until 38 weeks. While they can sustain themselves at an earlier age, pups usually stay with their family until the following spring and leave before a new litter is born.

Special Notes:
Here in Bella Vista, otters are uncommon. Little Sugar Creek provides a corridor for otters to get to Bella Vista and potentially all our lakes. In January 2020, an otter was seen eating fish in the Avalon heated dock multiple times. The Lakes and Parks staff may take measures to relocate the otter to prevent interference with the fish hatchery program. Although they are fascinating to watch, otters can be voracious and wreak havoc on a contained system like in a fish hatchery.

Carya (Genus) – Hickory

Scientific Name: Carya (Genus)
Common Name(s): Hickory, Typical Hickories (many different species)

 

Identification:
Hickory trees native to North America are all from the genus Carya, although there are 12 different species in the United States. All of them have different characteristics, as well as similarities. Hickory trees produce flowers in the spring that are small and yellow-green in color. The fruits are categorized as nuts that are surrounded by a hard husk with four parts. Husks split open when they mature. The nuts contained in the husks have a hard, bony shell that split in two halves when the seed germinates. Nuts measure 0.75 – 2” long by 0.5 – 1.20” in diameter.

cobblestonefarms.biz/hickory-tree-nuts/

Range:
Carya species are native to North America including southeastern Canada, eastern United States and parts of Mexico. Some species are native to China and India as well.

Ecology:
Hickory trees serve as food for many insects including the Luna moth, the hickory leaf stem gall and the banded hickory borer. Galls can potentially damage hickory trees, although they are normally harmless. Squirrels do more damage searching the trees for the galls to eat, and breaking off infected bark.

The nuts of hickory species can help identify the species of tree, although they are very difficult to identify themselves. All are surrounded by a husk that can be thick or thin but is generally hard through maturity. Some husks appear rougher than others and have slightly different shades of color.

The wood produced by hickory trees has a combination of strength, hardness, and stiffness that is hard to find in other woods grown commercially. It is used for many things that must handle a lot of weight and stress including bows, tool handles, lacrosse stick handles, golf club shafts, walking sticks, paddles and even floors. The heartwood is dark and highly contrasted to the sapwood making it very desirable for kitchen cabinets. It is great to use for cooking barbeque or smoking meats because of the flavor that it adds. The shagbark hickory Carya ovata has a bark extract that is like a smoky maple syrup.

Special Notes:
Here in Bella Vista, hickory trees are quite common on hillsides throughout the city. Shagbark hickory trees are one of the most easily recognized trees to identify by the bark. As the name implies, the bark looks as if it is peeling off the tree. There are others here including the shellbark, mockernut, and black hickories. All nuts are edible, but the reward for the effort required insures that most are left for the squirrels.

Species Profile – Odocoileus virginianus – White-tailed Deer

Scientific Name:              Odocoileus virginianus

Common Name(s):          White-tailed Deer, Whitetail

Identification:
White-tailed deer, Odocoileus virginianus, are most recognizable by the bold, white underside of their tails, which stands up straight when alarmed. In the summer adult deer have a thin reddish coat but is replaced with a thick brown coat around September. They have white on their undersides, insides of their ears, and beginning of their necks. Their ears are lined with darker fur, and there is white around their noses and mouths. Their hooves are separated into two parts with a split down the middle. Males, or bucks, have antlers that are shed and re-grown each year. Females are known as does, and young as fawns. Fawns are characterized by the white spots all over their body which they lose by 6 months of age. Bucks average 100 lbs., with does around 88 lbs., but weights are highly variable. In the northern parts of their range, deer are bigger in size.


Range:
Odocoileus virginianus is native to the United States, with a range including southern Canada down to northern South America. They have been introduced to other parts of the world such as Puerto Rico, New Zealand, and Cuba.

Ecology:
White-tailed deer prefer habitats with forest edges and open woodlands. They also like areas with dense vegetation for protection from predators. White-tailed deer are herbivores, consuming plants, grasses, fruits, acorns, clover, and corn. Deer can be considered a nuisance to farmers who grow corn or fruits that the deer will feed on and cause damage. In places with large populations of deer, they can have major impacts on native plants, although their browsing can help plant diversity in some areas. A deer’s home range usually consists of around one square mile, but this area is not in any defined shape, rather it is based on habitat, terrain, and home ranges of dominant deer. Deer can jump high fences and have a propensity to be a hazard on roadways.

Deer have many different calls they use to communicate with each other. Fawns will squeal, called bleat, if they have been separated from their mothers which will deepen as it matures. Adult deer grunt to each other to get attention, or a mother will grunt to find her fawn. When they feel threatened, deer will snort or blow to signal danger to other deer in the area and will raise their white tail while running away.

White-tailed deer in Arkansas breed from October through December with the peak usually occurring in mid-November. Breeding season is known as the rut. Males will breed with as many females as they can. Bucks will scrape an area with their hooves, clearing some ground and rub their antlers on the bark of a small tree to let females know that a male is in the area. They will urinate in these areas to leave their scent. Males may also fight with their antlers and hooves during territory or breeding disputes. Females release hormones and pheromones when they are in heat, letting bucks know they can breed. Females are pregnant for 6.5-7 months before giving birth. Females will nurse the fawns and hide them in dense vegetation for around 4 weeks to keep them hidden from predators. After that, fawns can get up and follow their mothers to search for food. Male fawns normally leave their mothers after a year, while females tend to stay longer.

Chronic wasting disease (CWD), a fatal neurological disease with no cure, has been found in some deer in Arkansas. It is caused by a protein in the brain that is abnormally shaped, called a prion. This disease can spread from direct contact between animals, or through contaminated plants. This disease causes deer to slowly waste away and become very sick. Humans are not at risk of getting CWD, although it is suggested that you should not eat a deer that has the symptoms of CWD. Also, there are some tick-borne diseases that deer are an intermediate host for, such as Lyme disease and Rocky Mountain spotted fever, which can be transmitted to humans.

Deer are popular among hunters for their meat, called venison, and for the antlers of bucks. Bucks will grow their first set of antlers when they are a year-old during spring and summer. Antlers are pure bone, although when first starting to grow, they are covered with blood vessels, nerves, and a soft layer called velvet. Growth can continue until September when the deer will start to rub off the velvet layer on trees or anything hard. Once the velvet falls off, the hard bone is left. Their antlers are shed around January-February.

Special Notes:
Here in Bella Vista, white-tailed deer can be seen virtually anywhere at any time. They are most active at dawn and dusk. Be careful of deer by roadways as they often run out in front of traffic. The second or third deer is often determined to follow the leader and often collisions with cars come from “the followers”.

Berksdale is Growing!

With 70 inches of rain (so far), it’s been a great year for growing grass! Now that we’re experiencing regular frosts, it is planting season. All our additions are selected in accordance with our Audubon International Cooperative Sanctuary standards for wildlife benefit and promoting native species, as well as consideration for flood plain management and aesthetics. Our experiments with growing our own trees and perennials were very fruitful this year and we were delighted to be able to invite volunteers to help get them in the ground. Switch grass, milkweed, and purple coneflowers were inserted in old fairway bunkers on our south end with help from members of the Northwest Arkansas Master Naturalists. Scout Troop 525 aided in planting sycamore trees, also on the south end, along the highway and corkscrew willows in a persistent wet zone. The Berksdale crew added red twig dogwood shrubs along old 18 creek bank and black willows along old 13 for stabilization. Corkscrew willows have been spaced throughout the grounds to help alleviate standing water issues. For more information, see auduboninternational.org, monarchwatch.org, and missouribotanicalgarden.org>plantfinder.

Golf Course Weather Closure Standards

The golf course superintendents shall have the authority to delay opening or closing their golf courses at any time. However, it will be a requirement that if delays or closings are necessary, the superintendent must notify the Pro Shop and golf maintenance coordinator.

Superintendents must report course conditions/closures to golf course maintenance coordinator and Pro Shop no later than one hour before first regular tee time. He or she must also stay in contact with Pro Shop on a regular basis throughout this same timeframe to keep them updated on course conditions.
During the winter months, we will continue to use the temperature as a guide, however, there are situations other than temperature that may dictate course delays or closures. The target temperature for automatic course closure is 35 degrees.

If the Weather Channel forecast for zip code 72714 is forecasted to be a high of 35 degrees or less for the entire day, then courses will close for that day. If it is forecasted to be above 35 degrees, then it becomes the golf course superintendent’s decision as to whether course opening will be delayed, or course closure is necessary.
It is extremely important that each superintendent take into consideration the importance of serving our members.

Bobcat

Lynx Rufus – Bobcat

Bobcat

Iucnredlist.org/Michael L. Baird

Identification:

Bobcats Lynx rufus are small to medium sized predatory cat’s native to North America. They have tan-brown fur with black streaks and spots scattered on their body with white around their mouths and belly. Their pointed ears are tipped with black fur. Fur sticks out around their face, making their head look wide. Their eyes are yellowish with a black pupil. They have large paws with retractable claws and long legs and their black tipped tail is short and stubby.  Adults are 19-49 inches long from head to tail and 12-24 inches tall. Bobcats weigh 14-40 lbs. with females weighing slightly less.

Map showing Bobcat area

Bobcat Areas

Range:

Lynx rufus is native to North America including most of Mexico, the United States, and southern Canada.

Ecology:

Bobcats are found in many different types of habitats, including all of Arkansas. They prefer woodlands but are also found in swamps, deserts, and rugged mountain areas. Bobcats can adapt given food and suitable habitat. Bobcats are solitary and occupy home ranges from 0.25 to 25 square miles. Females do not roam as far as males and do not associate with other females. Males are not normally tolerant of other males; however, their home ranges may overlap with other males and females. Territory is marked by urine, feces, and claw marks on trees. Bobcats are crepuscular, meaning they are primarily active several hours after dawn and before dusk. Behavior can change somewhat with the prey they are pursuing.

Bobcats normally have several dens for shelter in their home ranges. Predators of adult bobcats include humans, cougars, gray wolves, and coyotes. Kittens have more predators, including owls, eagles, hawks, foxes, and other adult male bobcats. Juveniles have high mortality rates in the few months after leaving their mothers. Diseases and starvation are other threats to the survival of bobcats. Bobcats are susceptible to parasites, both externally and internally. They carry ticks, fleas, and parasites of their prey. One mite, Lynxacarus morlani, is only found on the bobcat. These parasites are common on bobcats and are a threat to their survival, potentially causing more deaths than starvation and predation.

Bobcats consume birds, fish, insects, rodents, and other small mammals. They are a known predator of many domesticated animals including small dogs, cats, sheep, and goats. They often employ a crouch and pounce hunting technique for small prey much like a house cat hunting a mouse. With larger prey, they will stalk and rush the animal when they get inside 30 feet. With smaller prey, the bobcat will lie, crouch, or stand and wait for prey to come close before they pounce on it. Bobcats can survive long periods without food but gorge themselves when prey is readily available.

Breeding first occurs when bobcats are 2 years old. Dominant males stay with a female, mating with her several times from winter until early spring. Courtship may involve bumping, chasing, ambushing, and loud screams and hisses. Males and females generally mate with more than one partner. Normally 2-3 kittens are born after a gestation period of 60-70 days. Females raise the young on their own and they are weaned at around 2 months. At 3-5 months they can travel with their mother and hunt on their own within their first year. After they are able to hunt alone, they normally separate.

Special Notes:

Here in Bella Vista, bobcats could be spotted although they are mostly solitary. If spotted it would most likely be in secluded, wooded areas. Bobcats generally stay away from busy areas and commotion. Large cats may be mistaken for a bobcat, but they can be distinguished by the pointed ears, short tail, and generally more ornate color patterns compared to house cats. Bobcats themselves may be confused for a mountain lion; however, they are much smaller and lack the characteristic long tail of a mountain lion.

 

 

 

 

 

Species Profile: Butorides virescens – Green Heron

Scientific Name:              Butorides virescens

Common Name(s):          Green Heron, Little Green Heron, Green-backed Heron

 

https://commons.wikimedia.org/wiki/User:Basar (left), https://en.wikipedia.org/wiki/File:Butorides_virescens_070506_GWADA.jpg

 

Identification:

Green herons Butorides virescens are relatively small birds which can get up to 14 inches tall and have a wingspan of 25 inches.  Females are slightly smaller than males and their plumage is duller in the breeding season.  Adults have yellow legs and a long, dark, sharp beak.  The top of their head is blackish green and they have blue-gray on their back and wings that fades to green.  Their neck is brown with a white stripe down its length and a white chin.  Juveniles have reddish-brown and white streaks down their head and neck and many white spots on their wings.  Hatchlings have gray down feathers all over except white on their stomachs.  Adults have long necks but keep it pulled in close to their body at rest or while flying.

Range:

The green heron is native to northern South America, Mexico, and the United States.  They migrate north in late winter and early spring then head south August-October.

Ecology:

Green herons inhabit wetlands and other water bodies including wooded ponds, lakes, marshes, and rivers.  They make nests in trees or vegetation by water.  Nests are made of sticks several meters off the ground.  They are monogamous for a breeding season, with the male picking the nesting site and displaying courtship by flying noisily in front of a female with his head and neck feathers puffed out.  Green herons rarely congregate while nesting.  Females lay 2-6 pale green eggs in 2-day intervals.  Both parents incubate eggs until they hatch, normally around 21 days.  Both parents also feed the young and slowly wean them as the young get their flight feathers.  Young can usually fend for themselves when they are a little over a month old.  Occasionally green herons will breed twice a year.

Green herons consume fish, aquatic invertebrates, amphibians, crustaceans, spiders, reptiles, and small rodents.  They feed by stalking prey on the shoreline or from perched on branches above.  They are mainly active during dusk and dawn, hiding during the day unless searching for food.  They sometimes use “bait” to catch fish by dropping food or insects on the water’s surface to attract fish.  When the fish come for the bait, the heron will grab it.

Special Notes:

Here in Bella Vista, green herons can be spotted during their summer breeding season, mainly near the lakes or streams.  They are humorous to watch, especially when they sporadically extend and retract their long neck.

 

 

 

 

Scotsdale GCM Update 8/22

Scotsdale GCM Update

Recently at Scotsdale we have been working to improve the quality of our practice area, specifically the short game area and chipping tee. We have added two new irrigation heads to the tee area that previously was not irrigated. This will improve the quality of the chipping tee in several ways: the ability to effectively fertilizer it more frequently; better weed control; the tee will not have the tendency to get too hard when it dries out; and divots will recover more rapidly. These heads cover a lot of ground and in addition to the existing ones already near the target greens, provide a much better look to the area. It is just one small way we continue to strive in improving the quality of Scotsdale. I ask everyone to treat it like any other tee on the course and not drive or park your carts on the tee box.

In addition, we will be making an adjustment to the approach and fairway cut on #11. Due to how narrow it gets leading into the green, we experience some issues with the mowers used to cut the fairway. Our goal is to create a mid-section of rough in that area that will highlight the green more predominantly and prevent some of the mower issues that occur in this spot. We are making this change now since the weather will still allow for Bermuda growth and we can create this look before dormancy.

Future lines of where fairway ends, and approach/collar cut will begin for 11.

Thank you to everyone for your support and we hope that you have been enjoying the course!

Species Profile: Trachemys scripta elegans – Red-eared Slider

Scientific Name:              Trachemys scripta elegans

Common Name(s):          Red-eared Slider, Red-eared Terrapin, Pond Slider subspecies

https://commons.wikimedia.org/wiki/File:Turtle_with_Neck_Stretched_Out.jpg ©Dan Soto

 

Identification: Red-eared sliders (Trachemys scripta) are semi-aquatic turtles with a distinctive red-orange stripe behind both eyes that distinguishes it from other turtles. Their body is covered with green and yellow stripes and they have webbed feet with short claws. Their shell averages 6-8 in, with female red-eared sliders typically larger than males. Shells of young are leaf green and get darker as they age, becoming olive green-brown. The bottom of their shell is a light yellow with dark markings. The colors of their body and shell help them stay camouflaged. Red-eared sliders can withdraw their body into their shell for protection when they feel threatened. They spend most of their time in water, although do bask in the sunlight on logs or rocks close to or in water. The lifespan of a red-eared slider is typically 20-30 years.

Range: The red-eared slider is found from northeastern Mexico to northern Illinois. They are as far west as eastern New Mexico and as far east as West Virginia and a small portion of southern Ohio. Arkansas is at the center of their range.

Ecology: These turtles are typically found in any body of calm, warm, freshwater. They cannot regulate their body temperature on their own and must rely on the temperature gradients of their environment. They bask in sunlight to keep warm and submerge themselves in water to cool off. They are often seen on rocks or logs basking in groups, and rarely leave the water except to bask. These turtles are highly adaptable and can tolerate many different habitats.

Red-eared sliders are very popular as pets, so large numbers are commercially raised throughout the southeastern United States. The FDA has restricted the sale of the eggs and turtles smaller than four inches because of Salmonella infecting humans who have handled turtles. Reptiles do not show effects of having this bacterial infection. Therefore, healthy looking but infected turtles can pass the bacteria to humans, especially small children, who have them as pets. This can be prevented by teaching children that they need to wash their hands after they handle or feed the turtle.

Red-eared sliders are omnivores that consume insects, fish, frog eggs, tadpoles, and a wide variety of aquatic plants and algae. Adults are more herbivorous than the young, although both will opportunistically eat insects and fish.

Mating occurs from March to July. Males court females by swimming around them and brushing their head and face with the backside of their claws. If the female accepts the male, she will sink to the bottom to mate. If she does not accept the male, she will become aggressive. Courtship is a long process but mating only lasts about 10 minutes. Females lay between two and 23 eggs in each clutch, and up to five clutches in a year. When a suitable spot has been found, the female will dig a hole with her back legs and lay her eggs. There is no parental care for the young and sex is determined by the temperature of the environment with males developing at colder temperatures and females developing at warmer temperatures.

Special Notes: Here in Bella Vista, red-eared sliders can be found in the lakes, streams, and golf course ponds. The best time to observe them is on cool sunny mornings basking in the sun on floating logs or near water. The distinctive red spot on the side of their head can be seen from a distance and helps with identifying them.
