Helena,R. 1961 Crolia Bairdli 3 June Barrows, Alaska I heard displaying near the brock ridge. 4 June - 3 seen chasing near VOA's Area & in Britton's Area. 5 June Several noted Between Britton's & VOA's Areas. One courtship display was bluff-like. The display corbed his tail, lowered wing(dropped)-at speed, head held about normal & the ran off. The 2 - who kept on feeding. This was uninterpreted shots & both birds flew off. 8 June - Pr. observed S.E. of Britton's Area on The greasy bluffs overlooking family lagoon. When 1st seen, 1 bird (hereafter referred to as the 03) was displaying 30' off the ground. After 30sec.-so, he landed & began to feed. Gradually, he worked his way along a old caved out rut & the suddenly settled into a depression, which apparently will be the next site. He continued to squirm around, shuffling back & forth, apparently mating down the grass. He would lower down so that his tail & abdomen were up in air & he would scrape or press down with the lower chest again. The wings were spread slightly, but probably put in to allow the body full contact with the ground. To begin with he was fairly embroiled; I didn't think he began to turn. He would stand up
