A bird is larger than sparrow, but smaller than pigeon. The nest is found on a young pine at about 2 m above ground on 2 May, then 9 May. Russia, St. Petersburg, Pushkin, Kazanskoe Cemetry.

I'd suggest blackbird (Turdus merula)

did you see the bird?

I've never seen Black Thrush eggs with so many speckles with such a dark reddish-brown color. Plus, Thrushes prefer deciduous trees, shrubbery, thickets and bushes. I'm not an egg expert but I wonder about the Eurasian jay (Garrulus glandarius) in this case.

I think these are well within the range of colour and speckling for Blackbird. It is a species that usually nests in broadleaf trees and shrubs, but studies in Poland and Turkey report that nesting in pines is regular when other trees are not available.

I saw a female on the above-pictured nest 1 sec only. General coloration is brown, rather long and broad tail is also brown. Squeaking voice sounded quite displeased.

I can think of a dozen birds with eggs that resemble those in the photo. My first thought is Black Thrush but the pine tree is odd. In my experience, Black Thrushes are typically defensive. The male will be nearby and you should see him if the female is complaining. He will even examine the nest after you leave the area. Black Thrush is possible but there are other Thrushes. The Jay usually nests higher than 2m and you should be able to recognize it easily.

I've attached a photo of mine depicting the female Black Thrush for reference. The female can appear to be very dark brown to taupe with brown colors. Key is the yellow beak.
