R.B. Hamilton 1965 Falco rusticolus Borrow Alzake - Aug. 23 About 1700 a large falcon flew over pursuing pursued by a female Pomegrine Jaeger which was giving the "triple call". Both birds were about the same size and the Gyrfalcon was brownish. I was not thinking and thought that the bird was a Pomegrine Falcon. Dr. Pittocker saw the bird fly directly overhead and said it was a Gyrfalcon. On reflection I recall that the Pomegrine Jaeger is considerably larger than the Pomegrine Falcon. This hawk was flying N along Bixby Ridge over Toplins N 24° W. Aug. 26 A Gyrfalcon was observed flying E over Frist Lake. The bird was brownish with a top and below with the hood lighter. It appeared that perhaps the color was due to bird brown streaks on a whitish background. There was no moustache mark on the face. The bird was pursued by a flock of about 20 Dovewatches. Aug. 27. A Gyrfalcon was again observed flying N over Lino N and W pursued by a female Pomegrine Jaeger. This time I was able to identify the bird. I believe all three observations were made of the same bird.
