and cursing more difficult than Barrow tundra. One remarkable overall observation is
impression in the patchy distribution of birds along the transect, even w/o habitat patches.
Some areas have a lot of birds, others don't. A significant fraction of this can be
attributed to habitat distributions, with fewer birds in upland tundra. But even in
that habitat the birds are clumped. I will be interested to see how intensity of use
through the season varies in different units. MELT-OFF largely complete, with snow
cover extensive only in snowbanks. Last nights + this am's rain certainly hurried the
process. A few flying insects are about, diptera, hymenoptera, moths, and there are also
Colembola-like on pond surfaces. A few aquatic inverts beginning to be visible in the water.
