For the Birds: Yellow warbler no more; warbling vireo no more

Last year I wrote about finding a house wren and not being able to find it on the eBird list only to discover that the name of the bird had been officially changed to northern house wren.

Well, this year, there were two more similar name changes. First, the yellow warbler is now the northern yellow warbler. I think most people will continue to call it yellow warbler for years to come, but the familiar, loquacious yellow bird that nests throughout New England is, indeed, now the northern yellow warbler.

For the Birds: Don’t miss the action this spring

Spring migration continues to work its magic. 

My walks have been filled with migrants, including a few FOYs (first of years) each time I go out. On one recent walk, I saw a veery, red-eyed vireo, and American redstart, all firsts of the year. It’s always nice to see birds for the first time since last spring, summer or fall. 

The feeling is a little different for birds that we know are just passing through and won’t nest here. Of course, it’s always nice to see the first rose-breasted grosbeak, scarlet tanager, Baltimore oriole or ruby-throated hummingbird, but we know they will nest locally, and we will have plenty more chances to see them over the next several months.

Some birds, however, especially select warblers, will not nest locally, so if we miss them during their short window of passing through New England, we have to wait until fall to try to catch a glimpse of them as they pass through during their southern flight. If we miss that opportunity, our next chance will be the following spring.

For the Birds: The shore comes through again

The spring migration has certainly begun, but it is still in the building-up phase.

I took a few walks in the woods over the last few days and saw some very welcomed migrants, such as pine warbler, palm warbler, yellow-rumped warbler and Louisiana waterthrush. 

When migration is just picking up, however, the action can be hit or miss. In a few weeks, the action will be all hits all the time, and I’m sure we are all looking forward to that.

While those first migrants are great to see after a long winter, they also whet the appetite to see more spring migrants. The woods will be hit or miss for the next several days anyway, so the other day I went to a spot where I knew I would see a few old feathered friends that I hadn’t seen since last summer.

For the Birds: Winter finches starting to come around

I wrote about the winter finch forecast a few weeks ago. The annual forecast predicts which and how many finches will irrupt into New England from the north each winter. An irruption occurs when birds that are not typically seen in an area appear, sometimes in great numbers, during the winter.

Food, of course, is the main driver of these irruptions. If the seeds of a bird species’ diet are scarce up north, the birds will come south to find a food source.

For the Birds: Breaking down hawkwatch season

The fall hawkwatching season is winding down. Raptor sightings at the various dedicated locations are slowing down, with only a handful of birds counted each day as November progresses.

It’s a good time, therefore, to check in to see how the various hawkwatching sites fared this year. New England has several popular sites, but Pack Monadnock at Miller State Park in Peterborough is New Hampshire’s most active and popular site. The hawk count is a project of the Harris Center for Conservation Education in Hancock.

For the Birds: Fall migration under way

It seems like just yesterday we were welcoming back the warblers and other songbirds during spring migration and here we are at fall migration already.

Many of the birds we saw in the spring heading north will look the same on their southward journey. Many others, however, will look different. 

Some, like male scarlet tanagers, will bear little resemblance to what they looked like in the spring. When we saw them in May and June, they were the most brightly colored birds in the woods. A sighting always yielded a gasp of excitement as we wondered how a bird in New England could be so brilliant. After the breeding season, however, they molted and are now dull yellow with less shiny black wings. They are still awesome-looking birds but not the striking birds they were in the spring.

In addition to many adult birds molting, the fall migration includes first-year birds that haven’t attained familiar adult plumage yet. They often resemble females or a mix of male and female plumage.

For the Birds: Plumage challenges of late summer

The Cooper’s hawk I wrote about last week was a bit of an anomaly for me.

It’s not that I don’t see Cooper’s hawks often, but I typically see immature Cooper’s hawks. The one featured last week was an adult. Looking back through my photo collection, the vast majority of Cooper’s hawks I have photographed were immature birds.

With many birds, differentiating young birds from adults can be tricky as the time period between immature plumage and adult plumage is relatively short. With Cooper’s hawks, it’s easier as they retain their immature plumage into their second year. Bald eagles, similarly, do not obtain their classic white heads and tails until they are four or five years old.

As immature birds, Cooper’s hawks (as well as closely related sharp-shinned hawks) are brown with tan-streaked white chests and bellies. As adults, they are blue-gray with reddish-streaked white chests and bellies. Immature Cooper’s hawks have yellow eyes, and adults have red eyes. Interestingly, ospreys are the opposite with adults having yellow eyes and immatures having orange-red eyes.

Hard to beat an American oystercatcher sighting

They aren’t particularly rare, especially if you know where to look, but American oystercatchers are always a thrill to see. I saw these beauties during a short birdwalk at Connecticut Audubon Society Coastal Center at Milford Point the other day. One of the coolest looking birds in New England, if you ask me. Check out the youngster below.

More information about the American oystercatcher may be found here.

For the Birds: This trip up north was a long time in coming

It had been several years since I had been to Pittsburg, NH, a place I used to visit three times a year or more back in the day.

My visits gradually became more infrequent as I got older, gained work and family responsibilities and grew less inclined to make the long drive. Besides, moose sightings had become increasingly rare up there, while they used to be a sure thing. Moose had always been the main attraction for me and many others who visit there.

Even so, the area has retained a special place in my heart, and I often long to be there. I just wish I could teleport there with my truck, canoe and camping equipment.

Warblers up north

Here are a few warblers I saw on my trip up north. Previously, I had posted photos of loons and an eagle. Canada warblers and magnolia warblers are similar looking with their bright yellow chests and bellies streaked with black. There some obvious differences, such as the eyes. Canada warblers have an obvious eye ring, while magnolia warblers have a black mask with less obvious broken eye ring.
