Interspecific aggression of meadow pipit (Anthus pratensis) towards treepipit (A. trivialis), whinchat (Saxicola rubetra) and skylark (Alauda arvensis) and interspecific aggression of whinchat towards meadow pipit was tested in playback experiments at the beginning of breeding cycle (both species) and during the brood feeding period (whinchat only). Neither meadow pipits nor whinchats responded aggressively to the playback of the heterospecific songs. Whinchats, however, chased or attacked meadow pipits that approached it in response to the meadow pipit songs in the brood feeding period. I suggest that the aggressive behaviour in whinchat is triggered rather by visual than acoustic cues. Another series of playback experiments with meadow pipits was carried out to investigate the effect of the sensitisation caused by previous playback of the conspecific song on performance during the playback of the tree pipit song 30 minutes later. No clear effect was discovered, but some of meadow pipits reacted in a way more characteristic for the intraspecific experiments.
