Literally overnight it looks like two new and strange bird nests have been assembled under the eaves of the roof outside of our front windows.
I’m guessing that they’re bird nests because they’re connected up underneath the eaves and I don’t know what other kind of critter might be doing that.
I’m guessing that the one on the right is more complete. It’s not 100% clear to me what they’re made of – some kind of grass, but I don’t recognize it as anything growing nearby.
The one on the left seems only partially finished, but it’s the same design structure. I didn’t see any birds (or any other critters) around either nest, even though I was looking for them once I noticed that these were there.
What’s so surprising is the speed with which they had to have been made. They’re not subtle, I saw the long strands hanging down from inside the house, and on the outside they’re ridiculously obvious. I didn’t see a thing on Wednesday, even when I came home from the gym about 19:00, so this ALL had to get done this morning, assuming they didn’t work at night.
I ran the pictures through Google Lens to see if it could ID anything, but came up blank. I also looked on a couple of bird sites, including on the Cornell site, but found nothing. In simply describing “basket-type bird’s nest made of grass” the main hit was for orioles, and I have seen the large black & yellow hooded orioles around, but I don’t see any way these nests, as big as they are, could accomodate them. They’re big birds, almost as big as crows or ravens.
I did get one site that said that possibility was a Black-headed Junco nest, and I know we have those in the yard and the size makes more sense, but that’s a tenuous clue at best.
I’ll keep my eyes open and see what happens.
Does anyone recognize the nest design or have any clues to share?

can’t really tell from the pictures but they kind of remind me of those really long pine needles from the trees in the old backyard?

That was my first impression too, but this stuff is more fine & flexible, like long grass. The pine needles are thicker & more brittle, although there are tons of them available on the hill behind the back yard here too.

It looks like the grass is woven around the white cable , or is it just a trick of the photo? Try a search with ‘grass woven into a tunnel under the eaves’, and see what comes up. Also, just a thought – check where your hummers nest.
Intriguing, mystery man!

Those are plastic ties that I pit up there to support the Christmas lights & the nests are definitely woven around them for support. There’s nothing else under there to attach to.
