WILDLIFE MANAGEMENT NOTES

April 19, 2005

 

Weather

What an amazing Spring we are having! Periods of cool, clear air, low humidity, and then spates of heat, high humidity and torrential rains. We experienced flooding over the tops of several dams and spillways, especially after the intense rains of March 26 and April 4. Weve seen nothing like it in over a decade. For a week the roads were too sodden to drive on and even after two weeks since the April deluge the Spring Pond, Frog Pond and Big Bay Pond are still full to overflowing. Its doing the frog population good! We need to watch carefully as the water levels go down because woodstorks are attracted to a body of water that is shrinking. The oxygen levels decline and the surface area decreases, making it easier for storks to catch fish and frogs.

The last few days have been blissfully cool, sunny, and pleasant, with a very sensual northern breeze. It definitely inspires spring fever  its hard to stay inside!

 

Land Management

All this rain has had an impact on our burn schedule. Several burns have been delayed, but as of Saturday the 17th of April we have completed everything we planned. It has been extremely interesting burning in humidities of 25% - even two days after a rain the grass and pine needles are dried out enough to burn extremely hot. It makes for a lot of work for the crew to protect blooming wild azaleas and red buckeyes, but its worth it. Please come see the buckeyes  they are still in full bloom at the corner near the Gin House (see the mowed area) and along the western edge of the Wildlife Woods. There are still a few wild azaleas in bloom  they have been stunning this year  more than in recent years and fragrant beyond belief. They have consistently been attracting flocks of gorgeous swallowtail butterflies of all kinds. Some are still blooming in the Butterfly Garden, easy to see.

We are done with burning, but our land management goes on. There are numerous mowing projects to accomplish this year for brush control, especially winged sumac control in the Gin House Field. We always can use help from volunteers with invasive species removal. Japanese climbing fern, Ardesia, tallow tree, kudzu, and bamboo are all problem plants we want to prevent from getting out of hand. It is virtually impossible to completely eradicate them.

 

The Butterfly Garden is emerging into its springtime color and variety and is already attracting lots of butterflies. Were seeing plenty of spicebush swallowtails and many pipevine, tiger and giant swallowtails. Last week I saw my first zebra swallowtail, brightly colored and recently emerged.

Last week Peter, our gardener, happened upon a marvelous sight. He was trimming around the wild azaleas Betty planted in memory of Rhodie White, and noticed, about 1 = feet off the ground, two large moths right next to a very large cocoon on an azalea stem. The next day Cyndi and I went out to see if they were still there and to try out our new digital camera donated to us by Betsey and Charlie Cooke. They were Cecropia moths. The pair was still there, in flagrante delicto, mating, both clearly freshly emerged. One, substantially larger than the other, we assumed to be the female as she had an engorged abdomen and a wing span of at least seven inches. We got a few nice pictures which will be posted on the website.

These moths were impressive, not just because of their sheer size, but their coloring and pattern was beautiful, their antennae were huge, all their scales were intact, and their bodies were so furry. They were gone the next day.

The assumption also is that the female was the one that emerged from that cocoon and attracted a male from a distance by means of pheromones that he can detect with his antennae.

 

Purple Martins

The Purple Martins have been absolutely delightful, as they have every year since 1943 when Betty erected the first martin pole right by the back door. They are incessantly entertaining and easy to observe from the trail or the benches located nearby. They appear to have completed all nest building and are now sitting on eggs. Generally, when one walks by, several will look out and watch you walk by.

Its really a treat to see them down at the Farm Pond, our only really open body of water. Sometimes they will circle around and then go down to the surface for a drink. This operation is done very smoothly and sedately. Other times they fly in for a bath and there is nothing sedate about it  they fly in at speed, from a height, and splash right in, submerging for a split second and then on they fly. They do this repeatedly. (Or could they be fishing?)

Martin-watching really becomes fun when they start to feed their young. They are very intense birds anyway, but baby-feeding takes all their attention and effort. They appear to collect the largest item of food per expenditure of energy per hunting trip. Therefore dragonflies are the prey of choice. Babies wait eagerly, heads stretching out of the gourds, sometimes up to four per gourd. Feeding is swift, one baby gets the prize, with tail and wings sticking out of its bill until it can get the thing down, then off the parent goes. They are very hard workers, martins.

 

The Bluebird Trail

Bluebirds and other cavity-nesters are well on their way to laying or fledging their first brood of chicks. Bluebird Trail Monitors Alice Honea and Bob Bearss and other volunteers are reporting many hatchings of Brown-headed Nuthatches and Carolina Chickadees and many beautiful eggs laid by Eastern Bluebirds. Please consider helping these dedicated volunteers on their monitoring rounds  you wont believe how tiny a brand new baby bird can be.

 

The Gin House Field is full of crimson clover just beginning to bloom. Most children who visit get excited thinking the red blossoms are strawberries or raspberries! The terraces are prominently outlined in green right now and there is an abundance of pink sourgrass and lavender toadflax coming out. Orchard orioles are singing from high in the cherry trees; blue grosbeaks are chasing each other around; kingbirds, not shy, let you get very close before moving another few feet away. Flocks of palm warblers are flitting their tails. Of course there are bluebirds galore, in full courtship coloring and singing their hearts out. Its a very lively place!

 

Big Bay Swamp

Water continues to flood out of the spillway and the beavers are just biding their time until the flow slows down a bit. The Great Blue Herons are actively feeding chicks that look bigger every day. The water tupelo trees are leafing out fast, so come out soon if you want to watch the herons feeding. It is a raucous time: a parent arrives with food and there is much clacking and barking and other forms of heron jubilation. How two growing chicks and a full grown parent all remain standing on that small disk of twigs throughout such a chaotic greeting is beyond me. Its fun to watch!

 

Miscellaneous Observations

Recently arrived in their full glory are the Indigo Buntings and the Summer Tanagers. Both are singing lustily around the entire place. Cedar Waxwings are still here, cleaning up every last mulberry and Oregon grape. Wild Turkeys are gobbling in the early morning; Barred Owls are hooting all day long in the Live Oak Hammock.

Fence lizards are blending in to their tree bark surroundings; fox squirrels  all shades of silver to black  have been spotted in the woods; a few white-chinned black racers have also made brief appearances. The Farm Pond alligator is seen frequently now that we have burned the Upper Pond dam, basking in her own special wallow on the bank. Watch out when you walk by; she will thrash into the water and startle you. We are keeping our eye on her.

Another wood rat has moved into the nest under the outdoor restroom sink. We dont know if it is a male or female. It had a U-shaped wound on its right flank and limped when it just first appeared, but is now healed and we can identify it by the scar that remains. At first, in typical woodrat fashion, it climbed the mulberry tree at night and placed a large stash of stems with leaves and unripe berries next to its bed. After the Cedar Waxwings began coming through and knocking ripe berries to the ground, it now collects a pile of convenient ground level berries for its day-time snacking.

 

The Bird Window is a wonderful place to watch the gradual yet profound change of seasons. The bird population, both species and numbers, is in flux. As of April 1st we have seen new arrivals such as the Ruby-throated Hummingbird, Northern Parula and Prairie Warbler, Great-crested Flycatcher, Indigo Bunting, and Summer Tanager. We still have a few Pine Siskins, Chipping Sparrows, White Throated Sparrows (the males are very colorful), Gray Catbirds, and Cedar Waxwings. The American Goldfinches (called Wild Canary locally) have left already, the males turning a beautiful yellow. Weve been surprised by the persistence of several Fish Crows who love suet cake  such a large bird at the Window seems so out of scale. Ground Dove, Mourning Dove, and Northern Bobwhite Quail are enjoying the cracked corn, and the suet is vied for by Common Grackles; Red-winged Blackbirds; Red-bellied, Red Headed and Pileated Woodpeckers. Our regulars are in courtship mode and singing and nesting all around the Window and garden: Northern Cardinals, Carolina Chickadees, Tufted Titmice, Blue Jays, Eastern Towhees, Brown Thrashers, and Carolina Wrens. Unfortunately we have also seen a number of Brown-headed Cowbirds that parasitize the nests of many resident birds.

 

 

 

Springtime

What a truly lovely spring we are having. Every year is different and each is wonderful but this year feels so good! The equinox has passed; we are heading toward the summer solstice. Thankfully, many of us can take great pleasure in the beauty that surrounds us and the serenity nature offers so generously. We think of Betty, who passed away three years ago on April 16th, and honor her memory by enjoying and experiencing Birdsong, which was her lifes work and a gift to all of us from Betty and Ed. Birdsong is in a springtime state of grace and we hope you will come enjoy it.
