Mysterious bird in the kitchen.

[Flashingbeacon]

I’m just up after a night shift, popped into the kitchen to make a cup of tea and there was a dead blue tit on the kitchen floor.
All the windows are shut, DH and ds left at 8.30 (not mentioning any birds). We have 3 indoor cats who haven’t made a peep all morning and 2 dogs who have been snoozing on the bed with me.
Beak is bent and bloody but no other obvious injuries. When the cats are hunting a spider they usually knock down ornaments and create a racket.
What the hell happened?

Update, it was an adult blue tit. Helpful neighbour thought it might be a baby. Don’t know why that would make it more likely to be dead in my kitchen though.
Do I need to move all my furniture looking for more evidence?

Do you have a chimney?

Yes but it’s blocked at the bottom where the fireplace was. Do they have another hole? I’m assuming not but there’s a hole somewhere?

Stack pipe?
We had birds nesting in the pipe behind the upstairs loo one year. When they had flown the nest DH added blocking it up to the list of jobs he never gets around to, consequently we had a nest of sparrows the following year.

One afternoon I heard a thud, followed by or terrier coming flying into the lounge pursuing a small bird. The nest had dislodged, fallen down the waste stack pipe boxing and under the kitchen units where there was just enough gap in the kick board to escape.
No dogs or sparrows were harmed in our case thankfully. DH then blocked the hole.

Actually our downpipes come down the inside of the house rather than the outside (why?). Maybe there’s a gap somewhere. That needs investigating by someone on a ladder. Which is definitely not me. I can continue to do nothing except feel weird.
The lack of terror has me thrown though. There should have been commotion.

Look outside to where your bathroom is, see if you can see a small hole or anything like where a bird could nest. There are often some type of vent pipes there as well.
If it is that then it's possible fallen, crawled out and died which would explain lack of commotion, though certainly in our house there was one hell of a kerfuffle 😂

There’s definitely nothing like that in the kitchen though. It couldn’t have crawled very far without some kind of preditor noticing it.
Half the reason they are indoor cats is to protect the local bird life
