So, a robin built several nests in my carport, but only laid eggs in one of them, the middle one in the photo. They hatched about nine days ago. As you can see, the mother is not roosting in the middle nest, but that’s still where her hatchlings are. You can’t see them in the photo, but I saw them moving around in there. Is this normal? Does the mother just need her space or is she confused somehow, perhaps by the repeating joists? Is that why she built multiple nests to begin with?
If there’s another community where you think people might know better, please suggest it.
Update: all is well, apparently.
I’ve had some experience with seabird and waterfowl nesting research so this caught my attention. I haven’t come across anything like this personally, but I’ve only ever worked with larger birds with higher nest building costs and greater territorial behavior across seasons.
Apparently this is a common behavior with some bird species, and it’s baffled scientists for a while.
I managed to find a specific explanation for American Robins (excerpt below). I can’t guarantee the validity of this author’s ‘supernormal stimuli’ explanation, but it’s a compelling one:
I can see your reply just fine, and the supernormal stimuli explanation mIakes sense. Also, I think I found my answer here:
Like I said, the chicks are about nine days old, so the mother’s behavior appears to be normal. That’s a relief!
Yay, happy news :)
That’s a really informative and interesting answer, thanks for sharing all the details.
Also, I’m on Lemmy (via lemm.ee) and I saw your comment with no issue, just looks like any other comment to me.
If valid, this is fascinating.
Really interesting, thanks for sharing
