Introduction Mobbing is widely perceived as an anti-predator strategy seen mostly in birds Curio ; Caro Materials and methods Study area We conducted the study in a valley at an elevation of — m a. Census trials We performed series of bird census trials. Statistical analysis We used Spearman's coefficient of correlation to compare numbers of species detected in different phases of the census trials. Results Main experiment in During a total of 50 census trials in , 39 species were detected from which five species Common Swift Apus apus, Common Raven Corvus corax, European Kestrel Falco tinnunculus , European Crested Tit Lophophanes cristatus, Coal Tit Periparus ater were detected only after the owl decoy was presented, and one species Green Sandpiper Tringa ochropus was detected only after exposition of a Capercaillie decoy.

Though this seems like a dangerous, brave, or even foolhardy behavior on the part of the smaller birds, it is less dangerous than it appears. The smaller birds are usually quicker and more maneuverable than the larger bird, making it difficult for the mobbing bird to be captured. Defending themselves would not be worth the energy the target bird would have to expend in order to kill and possibly consume the smaller birds.

Thus, if harassed, it is easier for the target bird to just leave the area. So you might ask, but what about crows? A red-tailed hawk or eagle certainly has the talons and strength to reach out and grab a crow with its talons.

A crow certainly would be a large enough prey to feed their young. But again, the crow is more agile than either the eagle or a large hawk, and therefore able to outmaneuver the targeted raptor. So it is the same as with smaller attackers, the energy cost of pursuing and attempting to catch the crow is usually not worth the effort. According to the Savannah River Ecology Laboratory of the University of Georgia, bird researchers have reported that birds of prey will fiercely protect their nests.

Crows seem to know this and keep their distance. It is as though the area immediately around an active hawk or eagle nest becomes a no-fly zone for crows. If, however, the hawk or eagle is not near the nest itself, it seems that crows will harass hawks and eagles, and the raptor will again avoid a confrontation with crows. Check out this short Video of an eagle who is perched away from its immediate nest location being mobbed by crows.
