Oriole builds nest; construction goes quickly

Baltimore orioles have one of the most unique nests of all the songbirds in New England.

According to allaboutbirds.org, “Baltimore Orioles build remarkable, sock-like hanging nests, woven together from slender fibers. The female weaves the nest, usually 3 to 4 inches deep, with a small opening, 2 to 3 inches wide, on top and a bulging bottom chamber, 3 to 4 inches across, where her eggs will rest. She anchors her nest high in a tree, first hanging long fibers over a small branch, then poking and darting her bill in and out to tangle the hank. While no knots are deliberately tied, soon the random poking has made knots and tangles, and the female brings more fibers to extend, close, and finally line the nest. Construction materials can include grass, strips of grapevine bark, wool, and horsehair, as well as artificial fibers such as cellophane, twine, or fishing line. Females often recycle fibers from an old nest to build a new one. Males occasionally bring nesting material, but don’t help with the weaving. Building the nest takes about a week, but windy or rainy weather may push this as long as 15 days. The nest is built in three stages: first, the female weaves an outer bowl of flexible fibers to provide support. Next, springy fibers are woven into an inner bowl, which maintains the bag-like shape of the nest. Finally, she adds a soft lining of downy fibers and feathers to cushion the eggs and young.”

During my recent trip to Presque Isle State Park in Erie, Pa., I came across an oriole pair building a nest. We saw tons of orioles overall, but this was the only nest I found under construction. I was amazed at how much progress the orioles made in just one day. The first photo below was taken on a Sunday and next two photos (and the one above) were taken on a Monday. Nature is amazing.

State of the Birds rings some alarms

Below is the press release (without edits or opinion from me) for the 2025 U.S. State of the Birds report. Commentary will come in a later post. …

The release of the 2025 U.S. State of the Birds report was announced today (Thursday, March 13, 2025) at the 90th annual North American Wildlife and Natural Resources Conference in Louisville, Kentucky. The report, produced by a coalition of leading science and conservation organizations, reveals continued widespread declines in American bird populations across all mainland and marine habitats, with 229 species requiring urgent conservation action. The report comes five years after the landmark 2019 study that documented the loss of 3 billion birds in North America over 50 years.

Key findings from the new report show that more than one-third of U.S. bird species are of high or moderate conservation concern, including 112 Tipping Point species that have lost more than 50% of their populations in the last 50 years. That includes 42 red-alert species facing perilously low populations, such as Allen’s Hummingbird, Tricolored Blackbird, and Saltmarsh Sparrow—birds that are at risk without immediate intervention.

Red-winged blackbirds return in force

This guy showed up at my feeder a few days ago, marking the first time I’ve seen a red-winged blackbird at my feeder in many years. Today, during a walk, I saw dozens and dozens of male red-winged blackbirds, mostly flying overhead. Males show up a few weeks before females to scout out territories. The familiar sounds of red-winged blackbirds are back. The spring migration is under way.

For the Birds: Great Backyard Bird Count coming right up

I’ve seen a ton of robins this winter. On several occasions, I’ve seen them in big numbers attacking bushes and trees and stripping them of fruit.

I’ll always remember the first time I saw this spectacle. It was more than 20 years ago, and I was a relatively new birder. I walked into the woods and the trees were alive with bird life. Birds were darting from tree to tree all around me.

I was finally able to focus on a few and discovered that they were all robins. I was surprised because, at the time, I still thought of robins as spring and summer birds in New England. They are the harbinger of spring, aren’t they?

A few weekend surprises

I had a nice bird walk this weekend and found 24 species in the bitter cold. When I got home, I was treated to a surprise eastern bluebird sighting in the yard. Below, a winter wren was one of the highlights of the walk.

For the Birds: Christmas Bird Count thrilling as always

The Christmas Bird Count is typically one of my birding highlights of the year. This year was no exception. 

The Christmas Bird Count is a bird census conducted by volunteers each winter to track bird populations and trends. Keene was one of the original 25 locations in 1900. Now there are well more than 2,000 counts held throughout the United States and beyond.

I did my usual area along a coastal region of southwestern Connecticut. It is a good area to cover as there is a nice variety of habitats, including Long Island Sound, marshes, freshwater ponds, wooded areas and even some patches of open field.

We started, as usual, at a park that has a river on one side and a marina on the other. Long Island Sound is a mile or so to the south, so the river and marina often get winter ducks normally associated with larger bodies of water.

On Sunday (December 22, 2024), I participated, as usual, in the Christmas Bird Count and covered my usual area of coastal Norwalk (SW Connecticut). Instead of my usual birding partner Frank, I covered the area with Adam and Jo. It was 13 degrees when we started and didn’t seem to get much warmer as the day went on. In fact, the wind picked up and made it seem even colder. The things we do for the birds.

We had a successful day with plenty of highlights, including bald eagle, peregrine falcon, merlin, pipit, pine warbler, yellow-rumped warblerf and both types of kinglet.

Here are some photo highlights of the day:
