Double casualties

Description:

Unfortunatley, most of my window regularly get hit by birds - fortunatley, deaths are rare, but this is a first - two in one go.
The dove was untouched by the hawk - both died due to collision with a window.
The picture of the collision site of the dove shows lots of crop-milk, forced from the bird's mouth - the milk is sort of hard, yellowish flecks/small lumps of curd. The bird was obviously feeding young squabs somewhere in the conifers that surround the garden.
Out of interest, I weighed them - hawk ~260g, dove ~220g.

Birds regularly hit several

Birds regularly hit several of the windows here - some with curtains, some not, one is hard to get to so is mostly rather grubby. Probably the most frequent obstacle are the patio doors - they almost permanently have absolutely fascinating "impressions" of pigeons on them, picked-out in feather dust/bloom - sometimes they are perfect snap-shots of the bird in flight.
I doubt anything short of exterior curtains will stop them and losses pale into total insignificance compared to local cat predations, or even accipter predations come to that.

window casualties

Birds normally only fly into windows if there is one opposite, giving them the false impression that they can fly through your house. So if you don't want to obscure this window you may be able to reduce the carnage by fitting curtains to the window opposite.

In this case only true of the rather grubby window - it is part of the front porch.
By coincidence, I mentioned the incident to a neighbour and they too have numerous collisions with their windows. I obviously can't be certain but suspect that very few of their windows are opposite others, but I do know that they have blinds or curtains at all windows.
