R.B. Hamilton 1965 Calcarius lapponicus June 12 Barrow Alaska- Lapland Longspurs were first observed in the area s of ARL. The males sang after both on the ground and in the air. The song resembles the song of Eastern Meadowlark. These birds are the most common Passerine on the Tundra. Most of them seemed to be paired with 2 ♂ and ♀ always close together. June 13 A ♂ was observed giving a ground display to a ♀. He had both wings in the air and postured in front of her. She seemed to squint but nothing happened. On several other occasions females were seen squinting, possibly they were testing nest sites. June 14 Four pairs were observed along the route of my afternoon walk. All were observed only feeding. One male was heard singing but no flight song was given. It is believed that the weather was responsible for this lack of breeding activity. June 15 Several times several ♂i were seen within 5 ft. of each other without any interaction. Much singing was heard both from the ground and in the air. June 16 These birds were observed as pairs. No courtship was observed and only an occasional song was heard. June 17 The birds were observed in pairs. Much singing was heard from the males. A ♀ was seen flying with a fluttering flight. I did not see where she took off from. I searched the general vicinity and did not find a nest. June 18 The birds were observed in pairs scattered throughout the Tundra. Much singing and territoriality was seen.
