Great tit and pied flycatcher compete for nest sites

The pied flycatcher arrives in Estonia in the second half of April, at latest in May. Like the great tit and the starling, it constructs its nest in a tree hollow or a nestbox but since by May the greater part of suitable nest sites are already occupied by other birds, the flycatcher starts taking over already occupied nests. The fights may even end with the death of one part – the great tit is larger and stronger and usually manages to defeat the intruding flycatcher. In 2015 for instance I found in a nest box in Vana Kuuste in Tartu County two dead male pied flycatchers on the verge of a great tit nest with eggs. The great tit evidently was not seriously hurt since all chicks developed nicely.
