Feldlerche
This is a smallish lark, slightly smaller than the Eurasian skylark. It has a long, spiky, erectile crest. It is greyer than the Eurasian skylark, and lacks the white wing and tail edge of that species. It is very similar to the widespread crested lark. It is smaller and somewhat greyer than that species, and has a shorter bill. In flight it shows grey underwings, whereas the crested lark has reddish underwings. The body is mainly dark-streaked grey above and whitish below. The sexes are similar.
