SP Myers 1976 Journal 42 Transsects 31 July They are a small fraction of the number of juvenile posilla in the area now, almost all of them crazy liberal habitat. Indeed, the units in which they occurred were actually in the Accinella / Phippsia - Colydina area in units Oa, Ob of transect 6, i.e. Libral zone, the dried upper reaches of Voth Creek. One adult male is positively dead; if others are still around it would appear that their voice has changed. Up until now, at least, the most reliable sexual marker has been the gruff churr of the ♂, notably harsher than the ♀ call note.

The birds flew very little this morning, such that I knew I had very few, if any, duplicate counts. Note that adult melanootos (all ♂), and adult fulicarius (all ♂) are now outnumbered by juveniles. Also, it appears that golden plover numbers are dropping - as is also reflected by transect data. At Britton Ponds, Chuckchi Sea. App: Spent 2 hrs on the littoral zone this evening, from 8-9 and 10-11. First stop was the Britton Pond area, where I observed Calidris pusilla juveniles aggregating in a manner specific to space. My presence, however, was an obviously disturbing factor, so that if true territoriality were expressed, as Peter Conners reported, it was not evident - or consistently so - as I was watching. Conners and Jim Carlton, an incompetent geologist working for Conners, have taken cores from the area + report it to be extremely rich in chironomid larvae. I then walked over to the shoreline of the Chuckchi, which is now open water for ~200 meters out to sea. The invertebrate group has begun -
