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.

For the Birds: Wrapping up 2024 with the year’s birding highlights

Welcome to 2025, everyone. Without introductory fanfare, here are my top birding highlights from the past year.

10. I see more and more bald eagles every year. I’m not the only one, of course, as bald eagles are doing well as a species, thankfully. I visited family in Erie, Pennsylvania, over the holiday break and saw five bald eagles at Presque Isle during a single visit. I saw a few more on the drive home along I-86 in New York.

9. Hawks, particularly red-tailed hawks and red-shouldered hawks, are even more common than bald eagles, of course. On a few occasions this year, I came across cooperative hawks and got some good close-up photos. In a later column, I’ll show the differences between zoom focal lengths when photographing birds.

8. Overall, it was a slow year for ducks, which is disappointing considering ducks are my favorite type of bird to watch. My best “duck day” came during the Christmas Bird Count when I got close-up views of long-tailed ducks and American wigeons. I need to do better on my ducks in 2025.

7. A pair of catbirds and four purple finches were regular sightings at my local park throughout January and February. Catbirds do not typically overwinter in New England, but these birds had a reliable food source that kept them here. It was strange to see catbirds with snow covering all the surrounding branches. Purple finches are not uncommon winter sightings, but it was fun to see them daily, nonetheless.

For the Birds: A visit to Erie – a birding hotspot

When the peak of your favorite hobby lasts only a few weeks each year, you better make the most of that time.

For birdwatchers, that is spring. Specifically, the last week of April and the first two weeks of May. Of course, the spring migration started many weeks ago and will last into June, but the sweet spot is those few weeks.

As luck would have it this year, my niece planned her wedding for mid-May. The wedding was held in my old hometown of Erie, Pennsylvania. I didn’t know it when I was growing up, but Presque Isle State Park in Erie is one of the top birdwatching destinations in the country. Presque Isle is a peninsula jutting into Lake Erie and, in addition to the many birds that nest there, several others use the land as a stopover before crossing over into Canada.

Instead of going home for a long weekend, I took the week off and made a vacation of it. I visited the park for several hours on Monday, Tuesday, and Thursday. Each day I saw something a little different. On Monday’s walk, I saw 51 different species. I did not keep track on Tuesday’s walk as I wanted to focus on photographing some of the warblers.
