JPLayers 1975 Journal GRID 3 28 July (canto) Census totals alpina 3 melanotos ♀ 6 Ph. fulicarius 7 29 July remained inside much of day compiling transect information. weather miserable - 35°, rain. 30 July GRID 2 Ogis began sampling GRID 2. - during the census period weather changed from a thin fog with no wind to a clearing sky and light NW breeze. As I was returning to the lab at 1230 the sun shone briefly. Census totals: alpina 14 (including 4 juveniles) melanotos ♀ 3 + 3 juveniles Ph. fulicarius ♀ 12 Pluvialis ♀ 4 Obviously the alpina situation has changed markedly: 24 July there was 1 alpina present. Today's flush included 4 juveniles in two somewhat distinct groups. The juveniles were spread throughout the low (1, 0-4) region of the grid; i.e. in flush polygons. They were apparently moving to a certain extent with the Pluvialis. In addition to the counted juveniles, there were unfledged alpina in at least two distinct areas (see census sheet). Today I found the season's first fledged melanotos- 3 juveniles still w/ parent(s) in (0,6) area. Brent II had 3 hatched chicks (see appendix). The increase in Phalaropus f. is was certainly due to a number of apparently non-breeding ♀'s moving thorough (at least 1 they were not acting as if tending chicks). Another item of note was that I found a St. praninus eating an unfledged melanotos chick. It came after me and passed near its chick (in 3,10 region) and dropped something only to pick it up again. As the bird flew off I saw it dangling something w/ obvious band leg + thus gave chase. When the jogger landed next I ran at it, + the wild bird dash off saved the chick. Inspection revealed it to be a melanotos w/ primary pin feathers
