J P Meyers 1980 Anser albifrons Atkasook, on the Mcado River, Alaska 31 May Saw a few albifrons from the place as we flew in. Then an air trip out to the Tryagite grid I saw several flocks of 10-15. 2 June a few Anser seen as I left camp, flying by in pairs. Biggest group I've seen found in area of (26537) - approximately 90 in a single flock, down on the ground in puddles in sand dunes. At 1530 I saw first sign of breeding aggression - a bird chasing another very persistently up the river. 3 June Large flock still there at (26,37) ~ 1145 but broke up during afternoon. Many small groups - 2, 3, 4, 5 etc. flying every which way, "lakeliding". As I came to Butterfly Creek, Billy Bournell was there with his 2yr old daughter, hunting white fronts. He gave a stupendous invitation of their call, and they came in directly. 8 June Few flocks about but many pairs and single birds flying overhead all the time. 9 June Only saw 3 today, two on ground and one solitary flying. 13 June Continued to see small numbers flying around every day Barrow 19 June Remarkable number of albifrons still flying about, particularly east of Caroline Ridge See Camp Phenology notes for more detail 1 July Found Anser albifrons nest by Caroline Ridge - 6 eggs
