Latest For the Birds column: Answering some more bird questions

Last week I addressed a question that was submitted to me by a reader. This week I’ll continue to draw inspiration from my readers and quickly address some more questions and comments that came my way.

One question regarded a one-legged hummingbird. A reader delighted in the antics of a group of hummingbirds at her feeder. As many as four hummingbirds were visiting at one time. The reader noticed that one of the birds had only a stump for a leg. So, can a one-legged hummingbird survive in the wild?

Before I answer that, just a quick note to say that things are not always as they appear. Many birds appear to have only one leg, but often either the leg is tucked away into the bird’s body or the angle from which you see the bird makes it look like it is missing a leg. Waders (herons, egrets), shorebirds and waterfowl often stand on one leg.

But in this case, since the reader saw a stump instead of a leg, it’s likely the bird did indeed have only one leg. Obviously it’s not ideal, but birds that spend most of their time either flying or perched in trees, such as songbirds and hummingbirds, can indeed survive in the wild. Their wings

Procrastinators rejoice. I’m going to give you an excuse to put off a few chores for another month or so.

Do you have trees on your property that need to come down? Bushes that need to be pruned? Perhaps a field or meadow that needs to be mowed?

Well, I’m not only giving you permission (not that you need that anyway) to hold off for a while, but urging you to do so.

An interesting email came my way this week from a New Hampshire couple. They had purchased property about 25 years ago that at the time was an abandoned Christmas tree lot. Most of the trees are now dead or dying and need to come down. The couple, to their credit, wants to make sure the nesting season is over before they go forward with any of the work.

So, just when is it safe to take down trees or cut fields that may house nesting birds?

There’s no exact date, of course. In general, though,

Here’s my latest For the Birds column, which describes the differences between Snowy Egrets and Great Egrets. For the Birds runs each week in the daily newspapers of Norwalk, Conn., and Keene, N.H. If you are out of those areas, tell your local newspaper about For the Birds and perhaps the column can get up and running there, too.

Here’s the column:

There are not many birds out there that have feet a different color than their legs.

From the top of their legs to the bottom of their “toes,” most birds are uniform in color. With many birds, such as songbirds and small shorebirds, the topic is fairly insignificant because their legs and feet are so small and rarely seen Continue reading

How do birds know when a new feeder is out?

Here’s my latest For the Birds Column, which runs weekly in The Hour (Norwalk, Conn.) and The Keene (N.H.) Sentinel:

An interesting question came my way via email the other day. It came from a long-time Norwalk resident who wondered how the goldfinches in her yard knew that she suddenly switched to Nyjer seed. She had never seen goldfinches before at her feeders, but when she put up a sock feeder filled with the small, black seeds, the goldfinches came within one day.

“How did they know? Are they sock experts? Do they have X-Ray eyes that could penetrate the sock and see the thistle? Does thistle smell so they could sniff a trail? Do they have scouts always watching every yard?”

Great question. As a quick aside, what is commonly referred to as thistle seed is really either niger or the trademarked name Nyjer seed.

Whatever you call it, how do the birds know it’s there? Common sense may dictate that they smell it. How else could they know? But most birds, including our favorite backyard birds, have a poor sense of smell. Also, the seeds are largely odorless so even if the birds did have a strong sense of smell, it’s unlikely they’d be able to pick up the scent anyway. It’s not like a neighbor barbecuing chicken on a breezy day. The most likely scenario is that the birds saw the new feeder and recognized it — probably from past experience — as a food source. American Goldfinches are very nomadic  …

The answer is a definite “probably.”

I wrote my latest For the Birds column in The Hour newspaper (Norwalk, Conn.) about the topic.

Here’s the start of the column:

Now for the answer to the burning question in the Norwalk birding world: Most likely.

The question, of course, is: Did the Bald Eagles have babies yet?

Again, the answer is “most likely.” Without climbing the tree or somehow hovering above the tree on Chimon Island where the nest is located, it’s hard to tell with all certainty. Since no one is going to climb the tree or otherwise hover above it, it’s basically a waiting game.

The eagles are still out there and one is sitting on the nest at all times. You could see that from Calf Pasture Beach with a spotting scope or good pair of binoculars. In talking with Norwalk’s Larry Flynn, the eagles have been sitting on the nest long enough that eggs would have been laid and hatched by now. Flynn is monitoring the birds for the state DEEP.

The vantage point from Calf Pasture and, indeed, even closer from Long Island Sound, is such that only the adult eagle’s head and maybe part of its body is visible. There is no way to tell what, if anything, it is sitting on.

If there are actually eaglets in the nest, it will be several weeks until they are large enough to be seen in the nest. So we play the waiting the game. Hopefully our patience will pay off and eventually we’ll all get to see fledgings flying about Long

Project SNOWstorm seeks to unravel mysteries of the Snowy Owl

(Here’s a little something I wrote up about a presentation on Snowy Owls I attended on Sunday. The event “The Hidden Lives of Snowy Owls” was presented by Don Crockett and sponsored by Connecticut Audubon.)

Last winter Snowy Owls enthralled the U.S. Even casual birdwatchers couldn’t help but be caught up in the historic irruption of the beautiful, yet powerful Arctic bird of prey.

The birds made their way down from their Arctic breeding grounds in record numbers during the winter of 2013-14. Birdwatchers flocked to beaches to try to find the owls. Unlike most winters, the birdwatchers were often successful in catching a glimpse of an owl.

While Snowy Owls can remain in one spot for hours on end, they do move around quite a bit, during the day and night. So where do the owls go when they aren’t under the watchful eye of birdwatchers? What do they do at night when even the best spotting scope can’t keep track of their whereabouts?

Information about what Snowy Owls do when they come down to the United States is valuable because it gives us a better understanding of these mysterious birds. As Arctic breeders, the more we know about them the better as we continue to grapple with the effects of climate change. They may offer clues as to the extent to which climate change is impacting our world.

To help gather more information on these owls, a group of volunteers started Project SNOWstorm last year. The project involves trapping Snowy Owls with a net and attaching a transmitter to each owl’s back using a harness. The transmitter is lightweight (about 40 grams) and the harness is designed to not effect an owl’s flight. The transmitters are solar-powered, which reduces the weight as no batteries are required, and use the cellular phone network as opposed to satellites. Using the Continue reading

Latest For the Birds column — Far parking pays off again

Here’s my latest For the Birds column that appeared in The Hour and Keene Sentinel. A few months ago I wrote about the advantages of parking in a spot far away from my work’s building, so I could walk along the river to see what birds were around. Well, the practice paid off again.

Here’s my latest For the Birds column that appeared in last week’s The Hour (Norwalk, Ct) and this week’s The Keene (N.H.) Sentinel. It is about the northward movement of the territory of the Red-bellied Woodpecker, a large and handsome woodpecker that has been common in southern New England but scarce in middle New England. That seems to be changing.

Here’s the link to the story.

Thoughts from readers — what they are seeing out there

I often ask readers of my bird column, For the Birds, what they’ve been seeing out there in terms of interesting bird sightings. Every once in a while I compile the sightings and use them for my weekly birdwatching column. Here’s the latest, which ran last week in The Hour (Norwalk, CT) and this week in The Keene (NH) Sentinel.

I often ask readers: “What are you seeing out there?” Well, the answers I get are just as compelling and pertinent as what I see and write about each week, so here are some tidbits that readers have shared over the last few weeks. Why not start with Bald Eagles? Angela of Norwalk and Judy of Westport have written recently about Bald Eagle sightings. Angela saw her eagle in South Norwalk. The large bird of prey flew by her window and landed in an oak tree across the street where she often sees Osprey perch. “I hope it takes up residence here for the winter. I would be thrilled to see it again,” she wrote. Judy has seen her eagle perched high in a pine tree along the Saugatuck River. At one point, she witnessed the bird dive to the river and pull up a fish. Bald Eagles do visit more frequently in the winter, so perhaps this will be a good winter to see our national bird around here. A slightly smaller bird of prey has also been spotted several times by readers. I received a letter from Danny from Hampshire College who said an unidentified predator has been picking off chickens at the college’s farm. Based on the photo he sent, it looks a like a Red-tailed Hawk is the culprit. Gary from New Hampshire wrote to say he has seen Red-tailed Hawks on a few occasions catch pigeons near his home. Andy also shared a sighting of a Red-tailed Hawk in his backyard. He sent a photo, too, with the hawk peering down with a menacing look. He also sent a photo of an albino or leucistic Dark-eyed Junco. The photos, and other photos submitted by readers, may be found on my website http://www.birdsofnewengland.com on the “Reader Submitted Photos” page. I received an interesting phone call from Leona, another New Hampshire reader, who shared a story about crows in her backyard. “Bird brain” is often used as an insult, but we all know birds can be pretty smart, especially crows. Leona’s crows found a way to save trips while gathering and carrying away food. Leona put out crackers for the birds and instead of grabbing them and taking them away one at a time, the crows would stack the crackers and fly away with a bill full. Smart birds indeed. Finally, Joan shared a story about a lucky and determined chickadee. She saw the little bird hit her glass storm door. Expecting the worst, she approached the door to discover that the chickadee had actually gotten its foot stuck in a hinge of the door. Not wanting to let the bird fend for itself in that grave situation she grabbed a plastic flower pot and put it over the tiny bird. She then used a stick to free the bird’s leg. Joan set the flower pot on its side and took a few steps away to watch the bird. “He didn’t seem to be moving but was still breathing,” she wrote. “I then took a small container of water and dripped just a drop or two on his beak, which he quickly took in.” Here’s what happened next: “I was trying to decide what I would do with him overnight when all of a sudden, he moved his head, looked around at me and flew up onto a branch of a nearby tree about 15 feet up. He sat there for a minute, tipped his head to one side, gave a little “chhpp” and flew back toward the woods.” Joan concluded that “it’s nice to know there are still small wonders.” I totally agree. So, what have you been seeing out there in the natural world? Drop me a line and let me know. For the Birds runs Thursdays in The Hour. Chris Bosak can be reached at bozclark@earthlink.net.
