Hm, that's odd. It didn't happen to me either. I did report it but haven't heard anything back.

OK; going to check and see if the same thing happens to me...

I looked back through the North American ID forum and it doesn't appear that it has worked since June 28 when I reported it.

Thanks; I had noticed that eariler today but forgot to report it. I've done it now.

Just putting the mops away...

Unfortunately, no; I don't know of a way to delete your account or to change the name. You'd have to start a new account with a different e-mail address. By the way, sorry I misunderstood your purpose in posting the photo 😄 You might be able to guess the age by observing the robins as they leave the nest and mature. Bigger yellow gapes at the corners of the bill (where upper and lower mandibles meet), shorter tails, and more downy feathers and pinfeathers can indicate younger birds. For our Rufous-Collared Robins, the very young chicks have more spots on the breast and overall bronzy color; as they mature they lose the spotting and the brick-red color on chest and around the neck starts to develop. If you watch your babies you should be able to identify the patterns as they age.

That's a tough shot for an ID, but the colors look right. Can you get a clearer photo? I don't know that immature birds will help parents feed younger ones, but they might still hang out around the parents. Did you see the one you think is an immature Robin feeding young?

I'm sorry, I can't find a way to change your name, or for you to do it yourself.

That's true for many species; in some cases the females are more colorful (Belted Kingfishers) or simply very different colors (Red-Winged Blackbirds), but in lot of species male and females look the same, like Blue Jays, at least for humans! Apparently in some cases there are differences that birds' visual apparatus allow them to see but humans can't. But anyway in lots of species there's no way to tell, at least not just by looking at them. But like any animal individual birds are different, and sometimes you can recognize individuals if you spend enough time with them.

Let's stop the hate! If you are close to multiple species on a daily basis you learn to distinguish the sound of their wing beats. Exposure and spending time together leads to mutual understanding 😄

While you may have opbserved thses differences, you'd need independent confirmation that they are males/females to be able to say they are markers for sex. Otherwise it could just be minor differences between individuals.

Yes, I reported it.

Same on my computer. I reported it.

Are there other topics you'd like to read more about? (There is one about dealing with baby or injured birds at the top of the page.)

By twitter, do you mean chirp/vocalize? The ones I see certainly can be noisy but don't always chirp.
