The banded birds are back!

gray catbird DK7A2255© Maria de Bruyn resIn a previous blog, I described how six birds were banded in my backyard so I could track them over time. Bird banding has been done for decades, indicating that it is a practice that truly works for monitoring lifespans and locations of individual birds. But it still seemed to me that being caught in a net, having someone hold you as they extricated your legs and wings from the clinging threads, then putting rings on your legs and sticking you into a container (for weighing) would be a traumatic enough experience for you to decide that this geographical area was not where you wanted to be. Anthropomorphizing the banded birds’ reactions meant that I wouldn’t have been surprised (albeit very disappointed) if I had not seen the six birds again.

gray catbird DK7A2210© Maria de Bruyn resMy expectation was almost immediately proved wrong, however, confirming that birds do not stay away from sites where they were given their ankle bracelets. Corey, my tail-less gray catbird (Dumetella carolinensis) was the first one I spotted again, the very next day after the banding. He has an aluminum band on one leg and 2 red bands on the other.

Since the bands are such different colors, I decided to name the birds as that is easier to note down for sightings. The gray catbird with an aluminum band (they all have this color as it contains their registration number) and white and purple bands became Camden. The catbird with the lovely yellow and green bands was dubbed Clarissa. All three have been very regular visitors to the feeders, proving that a little discomfort was not enough to dissuade them from visiting the always available buffet of mealworms and other delights.

The catbirds have a fondness for sweets and like both apples and blueberries. Grape jelly is a real treat, for which they will return again and again.

He has not been a regular visitor, however – or I just haven’t caught sight of him among the bevy of other male cardinals that flit around the trees. However, a few days ago he turned up among the apples!

Carolina wren Willow DK7A2608© Maria de Bruyn resWillow, the Carolina wren (Thryothorus ludovicianus), has been a very infrequent returnee. When he comes, he tries to stay out of sight, choosing the side of the feeder away from me and only lingering a short while in plain sight. At least I know he is ok.

The one bird I have not yet seen is Rusty, the American robin (Turdus migratorius). I’ve been staring at the legs of every robin that hops around the yard but have yet to see one with leg jewelry. Perhaps he was just a stray visitor the day of the banding? I will certainly keep a look-out for him.

My first re-sighting data were entered into the Nestwatch site on 1 June 2015; it will be interesting to see how long I can maintain this input. Clarissa is a very frequent visitor so I think she will be in many entries. Or perhaps she is just busy right now feeding young ones.

The catbird parents are ever so vigilant and call out warnings to me whenever I approach the shrub. They hesitate to go into the shrub with food when I am near, even though those babies must be hungry. I finally got a view of them through the twigs when they were close to fledging. They are now hopping around on twigs in the shrub near the nest. Yesterday, when I came too close, Mama catbird dive-bombed, actually grazing my head!

The parents in both pairs are very diligent about bringing the babies meals, working as a team. One catbird parent seems to be good at collecting a variety of foods, in one case bringing three different insects at once (presumably one for each baby). I will look forward to seeing the young ones out and about and sincerely hope my neighbor’s cat doesn’t get them.

Bird watching is an enjoyable way to spend time; doing it and contributing to scientific data collection is even cooler!

Citizen science in my backyard!

Gray-headed catbird DK7A8986© Maria de Bruyn resIt’s been a while since I’ve blogged – not for lack of ideas and photos but due to a dearth of time and energy that was absorbed by multiple troubles with a few cool happenings in between. But now I’m back with some new observations about the beauty and happenings of interest in my natural world and I hope to share some wildlife sightings on a regular basis again.

One activity that I have managed to fit in amid the other goings-on was enrollment in two new (for me) citizen science projects for the Smithsonian Institute. I’m participating in an eMammal project run by the North Carolina Museum of Natural Science and in a multi-year observational study of some common birds. The mammal project is time-limited, so I will report on that in about a month’s time.

Northern mockingbird DK7A8859©Maria de BruynThe bird project will involve tracking visits to my yard by banded birds for several years to come. The target species include American robins (Turdus migratorius), Carolina chickadees (Poecile carolinensis), Carolina wrens (Thryothorus ludovicianus), house wrens (Troglodytes aedon), gray-headed catbirds (Dumetella carolinensis), Northern cardinals (Cardinalis cardinalis) and Northern mockingbirds (Mimus polyglottos, at the right), all of which come to my yard. Song sparrows are the 8th target species but I haven’t seen them at my house. However, I discovered that there is a great crested flycatcher in my trees, although I’ve never seen him (or her) either, so who knows if one will come in the future? In any case, the target birds can live from about 6-10 years on average, so I’ll have an ongoing activity for as long as my eyesight remains reasonable!

So how does the bird banding proceed? We (the bird bander and I) set up one 12-foot and one 6-foot mist net in two parts of the yard, after the bander laid out her equipment for the banding process. Within a very short time, we caught three birds in the large net! The first was a gray-headed catbird that I recognized (photo above), because he had molted all his tail feathers at once and looks a bit odd with no tail. This bird, whom I have named Corey, has been the most vocal catbird at my feeders and he was extremely vocal about having been caught as well.

gray-headed catbird IMG_3294© Maria de Bruyn bird banding IMG_3295© Maria de Bruyn

After being disentangled – very carefully – from the net, he was put in a bag while the bander got the other two birds out of the net. Corey was measured, weighed, and banded with a combination of aluminum and colored bands. Sex was determined (I now know he is a he!) and then he was let go.

Northern cardinal IMG_3311© Maria de Bruyn resBird 2 was a beautiful male Northern cardinal, who appeared to have good fat reserves. He was a bit vocal and bit the bander to show his displeasure at the treatment he was receiving.

Bird 3 was a male American robin. Sex was determined partly by looking at the cloacal region (outside breeding season, other markers besides brood patches and this area are examined). If a bander is unsure of the sex, this is also marked on the data sheet. The robin was more sedate during handling than his predecessors.

The house wrens had been calling loudly during the banding and flitted about in the trees and to the feeders,but they always flew just above the nets and were not caught. A male Carolina wren with a nice eye stripe did not escape.

American crow IMG_3359© Maria de BruynThe chickadees and Northern mockingbird flew about but did not really come too close to the nets. Non-target species were at or near the feeders, too, such as courting bluejays, an American crow (Corvus brachyrhynchos, right) who came to eat jelly and take some apple to his mate, downy woodpeckers, white-breasted and brown-headed nuthatches, a house finch, Eastern towhees and a male cowbird.

red-bellied woodpecker IMG_3344© Maria de Bruyn resOther non-target birds flew into the large mist net, however, such as a brown thrasher, a tufted titmouse, a red-bellied woodpecker (Melanerpes carolinus, right), a chipping sparrow (Spizella passerina), a female common yellowthroat (Geothlypis trichas, below) and a common grackle. I’d not seen these birds up so close before, so that was really a nice experience.

bird banding IMG_3340© Maria de Bruyn resTo get more target species, a loudspeaker that played bird calls and some model birds were placed in the grass by the largest net. Eventually, two more catbirds were caught – with other catbirds in a nearby tree puffing themselves up to show their shared distress. These were the first catbirds banded for the project so far, so that was a nice way to end the exercise.

Cope's tree frog IMG_3293© Maria de Bruyn resA tour of the yard to see if there were any nests that could be followed for the Nest Watch project revealed a couple wren nests in boxes that were built up so high it was not possible to see if they had eggs in them. The bluebirds’ nest has five eggs that I will follow through fledging (hopefully); a catbird nest is too high up for me to see how many eggs she is sitting on but I will watch for her fledglings, too. And a Cope’s tree frog (Hyla chrysoscelis) had taken up residence in the nest box that the downy woodpecker uses to rest at night. The wrens had begun building a nest in that box last night and the frog was gone this afternoon.

The banding took place yesterday in the morning and in the afternoon, the banded birds had not returned. I wonder how long it will take most of these individuals to come again. Corey already returned this afternoon, instantly recognizable not only because of his very short tail feathers growing in but because of the red and silver bands on his little legs. I was so glad to see he was none the worse for wear!

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.

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!

“Regal” members of the bird world

ruby-crowned kinglet IMG_2027©Maria de BruynWe usually don’t know who gave a bird species its common name and sometimes may scratch our heads wondering how and why someone ended up choosing a particular name. But birders faithfully learn to identify birds with those names, even when they may seem illogical. For example, many people would have chosen to call red-bellied woodpeckers red-headed woodpeckers since the reddish belly feathers are much less obvious than the red on the back of their heads.

Sometimes we can guess at why a bird got a certain name, however. The species with some form of “king” in their names were apparently felt to have something regal in their bearing or behavior. These birds don’t look similar though.

Some are quite small, like the ruby-crowned kinglet (Regulus calendula). This tiny bird, which weighs only 5-10 g (0.2-0.4 oz), is a bit dull in color except for the ruby crown that the males occasionally display. They are very active and very cute and having them leave the forest and woody areas to visit your bird feeders is a real treat.

Ruby-crowned kinglet IMG_9834©Maria de Bruyn res - Copy ruby-crowned kinglet IMG_2762 MdB (2)
The golden-crowned kinglet (Regulus satrapa) is even smaller, weighing on average 4-7.8 g (0.14-0.28 oz). The males and females both have crowns, although the males can have an orange patch in the middle of their crowns.

Golden-crowned kinglet IMG_7486© Maria de BruynGolden-crowned kinglet IMG_5785II
The tropical kingbird (Tyrannus melancholicus) is larger and has a crown stripe that is less obvious than the kinglet crowns.

Tropical kingbird IMG_8081X mdbTropical kingbird IMG_8113Z mdb

The belted kingfisher is larger still (Megaceryle alcyon) weighing 113-178 g (4-6.3 oz). The females are more brightly colored than the males, showing a reddish band across their breasts (both male and female juveniles have the reddish bands but adult males lose theirs).

Belted kingfisher IMG_5329©Maria de BruynresBelted kingfisher  IMG_9360f© Maria de Bruyn

Some birds don’t have regal names in English but do so in other languages. For example, in Dutch and German, wrens are called kinglets; in North Carolina, we talk about Carolina wrens (Thryothorus ludovicianus).

Carolina wren IMG_7891©Maria de BruynresCarolina wren IMG_8909© Maria de Bruyn

And then we have the large raptor (weighing in at 0.9–2.1 kg (2.0–4.6 lb) whose regal background is expressed in its scientific name, Pandion haliaetus. Pandion was the name of the Greek king of Athens who was grandfather to Theseus, who was transformed into an eagle. Haliaetus comes from the Greek word for sea eagle. We call this regal eagle by the simpler name osprey.

osprey IMG_0230©Maria de Bruyn resosprey IMG_9909©Maria de Bruyn

So these kingly birds are all quite different, ranging from the tiny kinglets to the robust osprey. What they do have in common is their loveliness, displayed in diverse size, color and plumage, and our appreciation for their beauty.
