Dining out in winter

cardinal and crowd DK7A9445© Maria de Bruyn resIn the spring, summer and fall, when birds have insects and other favorite foods available, many of us see moderate numbers of avian visitors at our feeders — although there are always exceptions, such as parents looking for easy meals to satisfy the voracious appetites of their offspring. Come wintertime, though, we may have whole flocks of different species flying busily to and fro to take food from our feeders.

 

tufted titmouse IMG_0635© Maria de BruynOur avian friends need to eat more, and more often, in autumn and winter to ensure that they can gain sufficient fat reserves to see them through the cold weather. Some of the smallest birds will consume up to 30% of their body weight. Nuts are a favored food for tufted titmice (Baeolophus bicolor).

In the autumn, there are still many berries available and these are a popular food. Birds that tend to eat insects much of the year will switch to berries in winter since their prey has died, is dormant and awaiting rebirth in larval form, or otherwise scarce. The berries of honeysuckle (Lonicera), privet (Ligustrum, an invasive plant) and other plants are popular foods for species such as cedar waxwings (Bombycilla cedrorum).

 Holly berries (Ilex opaca) are a favorite for American robins (Turdus migratorius).

Pine siskin IMG_6226©Maria de Bruyn resEven when much of the vegetation has dried up, seeds and seed pods remain. Pine siskins (Spinus pinus), downy woodpeckers (Dryobates pubescens) and American goldfinches (Spinus tristis) will feast on the seeds found in the pods of honeysuckles and trumpet vines (Campsis radicans).

In some cases, dried leaves and the remains of caterpillar tents form clumps that attract tufted titmice and white-throated sparrows (Zonotrichia albicollis) as they search for sustenance.

Pine siskins will eat moss growing on tree trunks. Other birds search the vegetation alongside ponds, like this song sparrow (Melospiza melodia).

The seed pods of my crepe myrtle trees (Lagerstroemia) are a magnet in winter for various avian species such as pine siskins, white-throated sparrows, red-winged blackbirds (Agelaius phoeniceus) and Northern cardinals (Cardinalis cardinalis), as well as Eastern gray squirrels (Sciurus carolinensis).

Various species of smaller birds will flock together in winter, both for purposes of safety and help in finding food. As the season progresses, the supply of seeds, pods and berries diminishes. In addition, the variety of natural plants has often decreased in urban areas as homeowners remove “weeds” from their yards. Wildlife organizations therefore encourage bird lovers to add native plants to their property, especially those that attract birds, and to provide extra food through feeders.

Northern mockingbird DK7A4279© Maria de Bruyn resMaking available mixed seeds, oil-rich sunflower seeds and suet (traditional or vegetarian made with vegetable shortening) will help the birds like this Northern mockingbird (Mimus polyglottos) keep up their energy. And it’s a good idea to keep those feeders filled — did you know that many songbirds are able to collect food in a special storage pouch within their esophagus so that they can then digest it after dark and overnight? This may help account for the fact that certain birds come back to the feeders over and over again within a short span of time.

 

The area where I live has had a long winter, with alternating days of relatively high temperatures and then very cold days and nights. Crocuses, daffodils and tulips are beginning to emerge in my gardens despite snow and ice and trees and shrubs are beginning to bud, giving the Eastern gray squirrels and house finches (Haemorhous mexicanus) a new source of food. I think that both the birds and I will be happy when spring arrives and stays! In the meantime, I’ll keep the feeders filled.

Russet-colored shorebird beauties – feminists among the waders!

ruddy turnstone IMG_8605©Maria de Bruyn resOne of my favorite shorebirds is the small sandpiper called a ruddy turnstone (Arenaria interpres). Their coloring is a mix of black, white and reddish colors, with adults being more brightly colored when mating and breeding.

These birds are very territorial during the breeding season; they recognize variations in plumage patterns and can identify individuals, which helps them chase away intruders into their territories. Pairs are monogamous when breeding and may mate for several years.

ruddy turnstone IMG_8651©Maria de Bruyn resWhen they fly, a stunning pattern is revealed in their spread wings, with striking white patches and bars.

The name turnstone comes from the fact that the birds tend to turn over stones while foraging for insects, crustaceans, worms and mollusks. Several birds may cooperate to overturn larger rocks. This carnivorous diet is supplemented with moss, fruit and berries. Occasionally, the turnstones have also been seen to prey on the eggs of other birds but this behavior appears to be uncommon.

ruddy turnstone IMG_0337©Maria de Bruyn resruddy turnstone IMG_8654©Maria de Bruyn res

They search for their food on rocky outcroppings, among stones, in sand and the ground, inserting their bills into the earth or flipping over seaweed to find meals hidden there.

ruddy turnstone IMG_8629©Maria de Bruyn res ruddy turnstone IMG_8619©Maria de Bruyn res

ruddy turnstone IMG_8782©Maria de BruynThese small birds breed in Northern arctic and tundra regions and then migrate South in the winter, quite often returning to the same wintering grounds each year. Their chicks leave the nest within hours after hatching and abandon the nest within a day. It is the males who take on the major childrearing tasks, guarding the territorial perimeters and warning the female when predators (owls, merlins, gulls, foxes) are near. They also show the young fledglings where to find food after the females have left to pursue other activities.

Outside breeding season and during winter migration, the birds are quite sociable. They have been seen preening and grooming for long periods.

The populations of ruddy turnstones are fairly stable and they are not threatened at this time – good news for the bird lovers among us!

Pines, habitat loss and endangered woodpeckers

longleaf pine IMG_0016©Maria de Bruyn resLongleaf pine trees (Pinus palustris) grow for 100-150 years before they reach full size and they can live as long as 500 years. Their extremely long needles give the young trees the look of a spike with grass growing out of it. At the tops of trees, the long, fanned out needles paint a pretty picture when silhouetted against the sky, even on overcast and dull days.

RED-COCKADED WOODPECKER IMG_9109©Maria de Bruyn RESUnfortunately, the longleaf pine forests have dwindled in size as a result of logging and this has contributed to the endangerment of a unique bird – the red-cockaded woodpecker (Picoides borealis).

 

The longleaf pine has a rough bark and plentiful resin, so much so that tree stumps impregnated with the resin will not rot. The heartwood of the old pines also becomes saturated with the resin.

longleaf pine IMG_9042©Maria de Bruyn reslong-leaf pine IMG_9025©Maria de Bruyn res

When the longleaf pine forests were still plentiful, the red-cockaded woodpecker evolved into a very specialized bird species as far as nesting is concerned. They mainly nest in longer-lived longleaf pines, preferring trees that are infected with red heart fungus as this softens the wood and makes it easier for the birds to dig out a nest cavity. They are the only woodpecker species that makes nest cavities in living rather than dead trees.

longleaf pine IMG_9035©Maria de Bruyn resThe nest cavities are constructed by a family of birds and completing one can take as long as two years (or longer). The families work on several cavities at a time and you will find clusters of trees with nest holes in given areas. The cavities are pecked out in such a way that the tree releases resin around the nest hole and you will see trees that are covered with long thick strands of resin coming down from nests.

The woodpeckers employ this tactic because the heavy flow of resin helps to keep tree-climbing snakes away from their nests, eggs and chicks. A breeding male will scout various nest cavities and then roost in the most recent cavity with the heaviest flow of pitch. The female lays the eggs and then the male incubates them during the night-time hours.

red-cockaded woodpecker IMG_9103©Maria de Bruyn resRaising the young becomes a cooperative effort as older sons remain with the parents and help incubate, brood and feed the babies. Family groups can range from three to nine or more members. The female offspring only rarely stay with their breeding parents as they move off in search of their own mates.

These woodpeckers mainly eat insects, including ants, beetles, roaches, and wood-boring insects as well as caterpillars and spiders. The family will forage as a group and sometimes also eat fruit and berries. Their abandoned nest cavities are used by other birds and small mammals.

red-cockaded woodpecker IMG_9152 ©Maria de BruynThe species is now considered vulnerable to extinction, with only about 12,500 of these birds remaining in the Southern United States. This is equivalent to about one per cent of the original population of this woodpecker. In response, there are now conservation efforts being undertaken to preserve the longleaf pine forests as habitat for the red-cockaded woodpeckers.

 

 

long-leaf pine IMG_0013©Maria de Bruyn resAt the Santee Coastal Reserve Wildlife Management Area in South Carolina, as well as in the Sandhills areas of South and North Carolina, forest rangers and others are working to enhance the longleaf pine forests for the birds. Controlled burns are clearing out dense undergrowth as the woodpeckers prefer sites with less deciduous growth; you can see them foraging quite low on trees.

In some areas, wildlife management projects are trying to help out the birds by creating artificial cavities, into which man-made nests are inserted. Restrictor plates around the holes also serve to stop other species from enlarging the holes or shape of the nest hole so that the red-cockaded woodpeckers will keep using them.

longleaf pine IMG_9040©Maria de Bruyn res longleaf pine IMG_9030©Maria de Bruyn res

At the Santee Coastal Reserve, several such nest holes can be observed alongside other trees where the birds are making their own nest cavities. Trees with nest holes are banded with white tape so that rangers can keep an eye on the woodpeckers’ activity.

It is heartwarming to see the efforts being made to restore the longleaf pine forests and the habitat for the woodpeckers – perhaps this will prevent this species from going extinct. And the National Wildlife Federation has stated that research shows that long-leaf pine forests will be especially well adapted to coping with environmental changes caused by global warming.

A bedraggled sort of day

Carolina wren IMG_4876© Maria de Bruyn resFirst, let this lovely Carolina wren (Thryothorus ludovicianus) and me wish you – fellow nature lovers and blog readers – all the best as we look to the future in this year of 2015! May your minor disappointments (life is not always rosy) be compensated by love, laughter, health and happiness in abundance!

 

Yesterday may have been a minor disappointment for the wildlife here.Hermit thrush IMG_3106© Maria de Bruyn res On Sunday, it was very cold for North Carolina standards. Together with two other Audubon Society volunteers, I was standing at a local lake in 15°F (-9.4°C) weather waiting to see if any bald eagles flew by for inclusion in the quarterly Eagle Count. We didn’t see any, although this lovely hermit thrush (Catharus guttatus) was nearby eating berries.

Monday was warmer but EXTREMELY wet! Two of my cats awakened me at 5 a.m. and I could hear the rain coming down in a veritable deluge. I wondered if I would be able to see the road to drive for an appointment later that morning (it did let up, thank goodness) and also wondered how the birds and animals were keeping in this unpleasant weather.

When it’s cold, the birds fluff up their feathers to trap air pockets by their bodies; this helps they retain body heat and stay warmer. Heavier wet feathers don’t seem to fluff well, though. On the other hand, birds’ feathers are covered with an oily or waxy substance that helps water run off, thereby keeping their bodies drier. Those feathers don’t necessarily look pretty though. Many of the birds were indeed looking bedraggled, some to a greater degree and others just a bit like these Northern cardinals (Cardinalis cardinalis).

red-bellied woodpecker IMG_5005© Maria de Bruyn resIt didn’t seem that many birds were hiding in vegetation to get out from under the downpour. Nope – they all appeared to be very hungry and anxious red-bellied woodpecker IMG_4948© Maria de Bruyn resfor a meal like this red-bellied woodpecker (Melanerpes carolinus), who was scolding me for being so close to the feeders!

white-tailed deer IMG_4092© Maria de Bruyn resA few white-tailed deer (Odocoileus virginianus) were also wet and hungry, including two visitors to my yard that I had not seen before. They were two bucks, one of whom must have been hit by a car. One of his antlers was broken off and he was hopping along holding up his left hind leg, which had obviously been injured.

white-tailed deer IMG_4055© Maria de Bruyn resA young doe, who visits regularly, stopped for some bird seed, as did the other buck whose antlers had been shed. Their thick hair was coated in raindrops.

The Eastern gray squirrels (Sciurus carolinensis) can curl their tails up over their backs as a kind of natural umbrella, both on the ground and in trees. This individual, who may have been injured by a predator and escaped, enjoyed some apple – first on the ground and then later in the tree away from the blue jays that were hopping around it.

Some of the birds definitely looked more presentable than other. The three visiting mockingbirds (Mimus polyglottos) were sleek and beautiful, one using its long tail tobalance as it plucked meal worms from a feeder designed for somewhat smaller birds.

The dark-eyed juncos (Junco hyemalis), Eastern towhees (Pipilo erythrophthalmus) and chipping sparrows (Spizella passerina) looked in fine shape, too.

The bluebirds (Sialia sialis) varied in appearance; a couple looked groomed but wet, while a couple others looked a bit disheveled.

pine warbler IMG_4569© Maria de Bruyn resThe pine warbler (Setophaga pinus) – usually among the more handsome garden birds – unfortunately looked a sorry sight. Fortunately, when the rain ends, he’ll be able to shake that water off and get back to looking like one of the handsome fellas of the avian neighborhood!

Growing up to be a redhead

Red-headed woodpecker IMG_9062© Maria de Bruyn (2)In the past month or so, I’ve been seeing red-headed woodpeckers (Melanerpes erythrocephalus) almost everywhere I go — except my own neighborhood! Jordan Lake’s woods in two different areas and various sections of the Mason Farm Biological Reserve have all provided me with multiple spottings of, and concerts by, these lovely birds.

I’m not very good at recognizing birds by their calls. Having listened to loud rock music as a teenager left me with some hearing problems. But the red-heads have a loud, unique, warbling territorial call that they emit frequently, regardless of whether another of their species is close by or not. I’ve become quite good at recognizing that call!

The juveniles begin life looking quite different from their parents. They have mostly gray-brown heads and backs and the part of their feathers that will later be entirely white are marked by black splotches and dots.

Red-headed woodpecker IMG_0742© Maria de Bruyn res

 

Like their parents, they show a variety of prey-hunting and food-gathering behaviors. You will hear them pecking at trees in their quest for insects but they also look for insects on the ground and can catch them during flight in mid-air.

 

Red-headed woodpecker IMG_0612© Maria de BruynThey also eat fruit, seeds and nuts like acorns and beechnuts, with plant materials making up about two-thirds of their diet. They will store food in caches so that they can find it again later during times of more nutritional scarcity. And in places far apart, they appear to be good at finding the same orangey cubes that are not nuts but some other, obviously delicious, substance.

Red-headed woodpecker IMG_9470© Maria de BruynTheir food storage habits help birders find them more easily. Both at Jordan Lake and Mason Farm, I’ve discovered a couple trees where certain birds have their food stash and if I wait long enough, a red-head is more than likely going to appear.

 

Unfortunately, due to habitat loss and changes to its usual food supply, this species has declined considerably in numbers. That is why it is so nice to see the juveniles among these various groups.

As they age, the brown feathers begin giving way to red ones, first around the nape and back of the neck. The black markings on the tail feathers begin to fade as well as they grow older.

 

 

Red-headed woodpecker IMG_9202© Maria de Bruyn resRed-headed woodpecker IMG_8734© Maria de Bruyn res

When they reach maturity, the birds have brilliant red heads, glossy black and pure white flight and tail feathers.

As these birds need dead trees for their nesting and storage cavities, it’s great that our area has some preserved forests where they currently appear to be thriving. And I can continue going out in the hopes of one descending from treetops to a lower and nearer perch so that I can finally get the stunning shots I’ve been wishing for!
