Bright chirpy song, very hard to see let alone photograph. This shot was the best I managed.
No interactions present.
The first picture is not a Skylark, but is probably a Meadow Pipit. The second bird, in flight, does look like a Skylark, so that is what I am agreeing with.
My Flickr photos...
Thanks Ophrys, removing the first photo
