There are very few birds of prey here due to persecution, but I know Arruntus has had probs with the H520 attracting the attentions of peregine falcons in Spain. Colour certainly has an effect on bird reponse. I have been able to get good video of shore birds with the Typhoon H (and you have to be very close for that). Most gulls ignore the H until it is a few metres away, then fly off, but I've had a few encounters with aggressive gulls that swoop at the H. These avoid striking it and if ignored, seem to lose interest. Corvids are much more wary. Put the H520 up and birds quickly find somewhere else to be, but as said, not many raptors here.
