Two days back I found this great site from Vogelbescherming Nederland (Birdprotection). They put webcams on birdnests. Result: 24 hours live view! You can watch the operations of the parent birds and their chicks live. There is even one 'normal' nests' : koolmezen (9 eggs!) - but also nests of birds of prey. And that caught my and hopefully also your interest.
You can, for example, follow the nests of a Kestrel or an Owl - and in the nest of couple of Peregrine Falcons you can watch their 4 chicks!
Nice and soothing to watch - this despite the pigeons that are torn to small bloody pieces before they disappear in those tiny beaks...
