cockatiel hasn't been pooping today

[udrop]

My 11 year old male cockatiel has not been pooping all afternoon, and possibly all day

Since I cleaned his cage today- about 7 hours ago, I haven't seen a single poop. There is urine(clear), and if there is any urates, it isn't visible because the paper I use in his cage is white (but now having him out of the cage, and peeing once, there are normal white urates). I had a friend over so I wasn't paying attention to his behaviour - but now I've noticed he is also straining when trying to poop. I haven't noticed if he's been eating, but I don't think he has much today. He was perched at the top of his cage, probably trying to sleep, or playing at the bottom, from all I've seen during my friend's visit. I noticed him eating and drinking normally now that my friend left.

About thirty minutes after my friend left, I've had him out. He's been straining, trying to poop at least four times - each time passing a bit of pee and urates, but no poop.. until he passed an undigested, abnormally largish piece of what looks like a seed. I'm guessing he must have swallowed it whole by accident, and then had trouble digesting it. Maybe it was a seed that didn't actually belong in his seed mix? Anyway, it is hard, not soft at all, and surrounding it was very gooey green, translucent stuff... I can't tell whether it is urine mixed with poop, or what it is. Accompanying it was a small chunk of white urates. I can only compare the goo it to mucus in human feces... maybe it was there to help pass the hard seed?

He hasn't pooped more since then - about 20 minutes. I encouraged him to eat and drink a lot after passing that seed, thinking maybe he should be alright now, but please, any advice would be appreciated. There are no vets in my area that I can get to at this time.

edit:: I just noticed he also sounds like he has a runny nose, now listening to him eating.. but that might be unrelated and just water in his nostrils or something

Sounds ill, best precaution is to take him to the vet first thing tomorrow if things don't change. Keep the bird warm and monitor food intake until then.

Thank you! I will do that if the problem will remain

he has now pooped three times since passing that seed - once with a good amount, others with little, but it is still great to see. He's been eating a lot now as well. I think he'll be fine but I'll keep an eye out c: I am so relieved. I hope things will indeed turn out fine. If they do, would it still be necessary to take him to a vet?

Just watch him carefully and use caution (meaning, if you see anything that looks out of the ordinary, rush him to the vet). But, are you sure it's a he and not a she? Because what you describe sounds like a female passing a soft-shelled egg (do you provide calcium and vit D3?)
