Red-necked grebes become semicolonial when prime nesting substrate is available

Red-necked Grebe (Podiceps grisegena) Science Article 1 abstract During 1995-1998 we studied the dynamics of nesting dispersion in a population of 160-200 Red-necked Grebes (Podiceps grisegena) on Lake Osakis, a large, windblown lake in central Minnesota. Breeding grebe pairs arriving on the lake were highly attracted to several large floating cattail (Typha angustifolia) mats that […]

Intruder pressure explains more of the variation in territory size than fish abundance for Red-necked Grebes (Podiceps grisegena) breeding on small boreal lakes

Red-necked Grebe (Podiceps grisegena) Science Article 2 abstract In the Red-necked Grebe (Podiceps grisegena), breeding pairs use both overt aggression and ritualistic behavior to defend territories for breeding and feeding. Examining the influence of factors determining territory size simultaneously continues to be stressed in studies of territorial systems. The behavior of grebes breeding on small […]
