is noticeable that Accipiter is attracted by a dog pack and their yelping and if the dogs are unaccompanied by humans will perch on a coconut near the swamp and watch. I never actually saw one attack or strike but usually they depart on the first sign of humans appear but they are exceedingly vigilant and wary. They possibly gather, to strike unexpectedly at the rails occupied with dodging the dogs but in observer's opinion it is not the rails that are the quarry. Bold and excitable birds such as Lichmera and Zosterops nearly always gather in excited mobs to swear at the dogs from a safe distance and it is these which Accipiter hopes to surprise while their attention is concentrated on the dogs. I once saw Falco at a great height watching a hunt but this I think was accidental, the bird having merely noticed the harried quarry moving from cover ahead of the dogs and this was probably a duck or its young as one later broke cover but Falco broke out of its swoop on sighting humans though I noted it kept high but in the direction the duck took and quickly forced the duck down to cover again. I was rather surprised at this instance as it was I believe the first time I noticed Falco shy off humans. Generally speaking they are very bold and will take game from the near presence of humans with great boldness. Possibly the barking of the dogs unnerved it in this instance. Severe hurricanes when they come, which generally is at wide, eight to ten year intervals doubtless cause a high mortality in birds especially in certain species (see NYMPHICUS Ibid) but these are at such wide intervals that probably little effect is made on the majority of the species if considered over a period of years. Under natural conditions and ample food and few un- usual or outside interference or influences to contend with, the
