Nothing in your observation rules out meadow pipit, which will often perch in trees at this time of year, especially if they are alarmed as you approach their nest site. The song is completely different though; you can hear a sample on the RSPB site at http://www.rspb.org.uk/wildlife/birdguide/name/t/treepipit and http://www.rspb.org.uk/wildlife/birdguide/name/m/meadowpipit for meadow pipit
