Birds in Chimney

Postby Eagle1Division » Wed Jul 13, 2011 1:24 pm

Hey, I've got a problem, and I'm not sure exactly where or who to ask, but I decided if there's a biology forum on the web then these guys might be knowledgable, but I'll ask my vet as well to verify, but I've got a bit of a situation as follows;

A long time ago we started hearing chirping in our chimney. After awhile we realized some birds has built a nest in there; the flue's always closed and we haven't used it in more than a year. Well, it's been really funny to hear chirping in there every time there's a noise or just every so often; but today I just realized there might be a serious problem. There's a whole lot of chirping that's been getting louder for a long time, and I can only assume that there's chicks growing up in there. They're quiet loud now, and I jokingly told my brother; "I wonder when they'll fly off?" - then I realized - will they?

They've grown up in the chimney, which I can only assume is extremely dark - so their vision might be seriously impaired in development - and they could even be totally blind. The Chimney has a cover over it so very little light ever gets in.

What's more - how will they learn to fly if they're currently living in the bottom of a chimney? Don't birds need to be up high in a nest to learn to fly?

So, I guess the question is: Will they die if we don't take care of them? When do we need to take care of them?

Another horrible realization I just had is could there be waste building up in there?

It's a long post, but thanks for sticking 'round. I hope I can get some good feedback.

Do not worry for the birds, if the parents build their nest here, they know what they are doing.
Do worry for your chimney though, I am no expert, but I can assure you that yes it will be a good occasion to hire a professional to clean your chimney, because that is definitely a fire hazard.

I'm not totally sure about trusting them... I think animals are smarter than people think, but I don't think birds have enough forethought...
They probably found the place, it was dark, enclosed, safe from any predators, and they felt safe, and instinctually built the nest there because it felt safe. I don't think they thought ahead and said to themselves: "I'm going to have eggs one day, and raise chicks wherever I put my nest. So I need to do it an an open area where my chicks can learn to fly". Nor do they know that a long lack of light during young development can stop a creature from developing sight... That's a scientific discovery we humans just made in the last century, IIRC. It's probably not that dark in there, though...

I just don't see how they can learn to fly in that tiny, enclosed space. And they need to learn to fly in order to leave that enclosed space. Deep holes like this aren't natural, with maybe some very rare exceptions... They can't get out unless they learn to fly. And I think they need an open area to learn to fly. So it seems like they'd be trapped.

Birds put nest to lay egg, not for anything else. Birds that are not smart about nest placement do not have a lot of offspring...
I might be wrong, but I would trust the birds for the placement of the nest. I would not trust my chimney before it has been clean though...

I agree with canalon. The birds are not building nests just for fun, but to have offspring. And even if they were not able to get out of it, it will be an experience for the parents, where not to built the nest next time ;) Although that may sound cruel, but that's the nature ;)
Anyway, even the parents must go inside somehow, right? And I doubt, that they are going through narrow and tall chimney. Rather they have the nest somewhere on top, but you are able to hear them anyway.

Cis or trans? That's what matters.
