Behavioral level and incubation behavior plasticity in marsh tits (Poecile palustris) and oriental tits (Parus minor) in response to pulsed and prolonged risks of nest predation

Nest ID; Species (MATI = marsh tit; ORTI = oriental tit); Nestbox type (SMALL = control; ENLARGED = treatment; prolonged risk); Playback stimulus (DOVE = non-predator sound; MAGPIE = nest predator sound; pulsed risk); Clutch size (number of eggs per nest); Incubation period (days; clutch completion = day 1 of incubation); Nest predation (0 = fledged; 1 = depredated); Ambient temperature (ºC); Nest attentiveness (%); Male incubation feeding trips / hr; Female foraging trips / hr; Detected numbers of corvids (within 50 m for 5 mins); Vigilance time (%)
