But it was heartbroken to look at the broken wing and also it can not walk on the ground, and it was very afraid

What did the vet say?

Unfortunately, I don't know right now
My friend, who found it, took it home, and said, that he would take care of it. I'm waiting for information from him soon. I hope, it would be fine

I hope he knows how to catch moths to feed it.

Hi, everyone!

Definitely not a Numenius phaeopus. They arrive by us only about in middle April and their call is different. I'm not sure but I think this simply is sound from flying ducks

pity, not an earlier arrived Numenius phaeopus. I never heard him. i' ve found a recording of its call, made by Uku Paal. in the beginning of the clip (somewhat) similar-sounding

Thank you, vainamoinen.

never heard this voice yet. i suppose a kind of loon?

A house sparrow with white head

sparrow has white patch of leucistic feathers
leucism, or leukism, is an abnormal plumage condition caused by a genetic mutation that prevents pigment, particularly melanin, from being properly deposited on a bird’s feathers
this bird appears repeatedly this season on the feeder

Yes Solo ... I've read about leucism but I did not know if this house sparrow is also leucism.
Yes, he comes to feed in Makov

Thank you Solo

btw. these are eurasian tree sparrows - Passer montanus, see e.g. https://scottishwildlifetrust.org.uk/20 ... e-sparrow/

OK Solo ... I understood

Interesting article! It could also be a partial albino.

What Can Cause Birds To Show Weird Color Variations?
Partial albinos are much more common, and most birders eventually see at least a few of these individuals. The term partial albino describes a bird that is paler than normal, or a bird with irregular patches of pure white feathers. There are several different causes of partial albinism—it can be genetic, occur during development, happen as birds age, or after injury when new feathers lack pigments—and it is a useful general term as it can be impossible to determine why a bird is showing pale plumage without a genetic analysis. Birds with partial albinism may retain plumage patterns typical of the species, such as a mask or wingbars. Here are some reasons animals show partial albinism:

Liz, thanx
- in your source they wrote about hypomelanism, leucism and age + injury as reasons why animals show partial albinism
- they are various types and causes of aberrations in plumage coloration in birds - see e.g. https://www.researchgate.net/publicatio ... n_in_birds

EDIT:
Liz, I have answer from one ornithologist: "it is interesting in sparrow I have not seen something like this, but I think it is a partial leucism"
