Saker Falcon (Falco cherrug) Science Article 2 abstract This study describes the species compositionof insects reared from larvalassemblages collected from Saker nests.Eight coleopteran and one dipteranspecies had been reared, none of whichappear to be specific to raptors’s nestsas a habitat. They are either characteristicto carcasses, or known to occur inmanure, or commensals living in a […]

Kestrel (Falco tinnunculus) Science Article 1 abstract To investigate time, energy, and temperature constraints on hatching asynchrony in Eurasian Kestrels (Falco tinnunculus), we observed females during the laying period and quantified the time spent hunting to see whether this might limir time spent incubating. We predicted that females would hunt more in years when the […]
