Well thats very reassuring. Thanks for the detailed reply.Well she's called scruffy for a reason!
So far it seems that the more eggs she has the more she seems to wake up to either change her position or to rotate the eggs themselves in to different positions.
I've watched them roost over the winter and that breathing pattern while sleeping seems to be fairly normal. If anything it seems to be related to the temperature I've noticed it more in cooler weather.
Birds don't sleep like we do. They shut down one half of their brain and keep the other active for self preservation reasons. They can appear quite restless.
Despite multiple visits to my nest box a few weeks ago, they decided not to nest. I've been up to take a look and theres a hole in the roof, so I'll replace the box and hopefully they'll be back next year.![]()
They nested last year so fingers crossed it's just the roof that put them off.That's unfortunate but I'd say if you had lots of interest that's a good sign for next year and you may get some roosting over winter too.

Blood flow increases around this area of skin and blood vessels become engorged. The brood patch is placed directly onto the eggs to transfer body heat allowing the embryo to develop under a steady temperature. The average egg temperature for birds is about 34˚C while the average body temperature is 43˚C. The brood patch remains throughout incubation and into the early stages of brooding the young. The photograph shows detail of a female Great Tit with a brood patch at ‘stage 4’ where the patch is less engorged, paler and with wrinkled skin once eggs have hatched and the young are growing in the nest.
Six of our eggs have hatched so far, the camera *should* be viewable using something like VLC
In previous years we had the mother leave the eggs for the entire night without a problem.
