> Lesser Yellowlegs: 212 adults and juveniles on Aug 3. There has been a

> Red-necked Phalarope: One on Aug 3.

> SHOREBIRD BREEDING POOR IN 2018: It was an overall a poor breeding season
> for shorebirds in the Canadian Arctic. A poor breeding season was also
> reported in Greenland and the North Slope of Alaska. The situation this
> summer was mainly a delayed (late) snow melt such that many birds did not
> breed. Those birds that did nest late had low success. Summer storms also
> caused nest abandonment and many nests were depredated. Paul Smith of the
> Canadian Wildlife Service commented, "I expect that juvenile numbers should
> be low, but I would be happy to be wrong."
> 
> SELECTED BIRD SIGHTINGS: American Black Duck, 21 on Aug 6. Black Scoter, 685
> mostly molting males on Aug 6. Bonaparte's Gull, 591 on Aug 4, almost all
> adults some starting to molt, couple of juveniles. Little Gull (3), adult,

> Flycatcher, 1 on Aug 4. Northern Shrike, 1 juvenile on Aug 3 and 5th. Canada
> Jay, 3 regulars but not tame. Boreal Chickadee, 3 on Aug 3, regular.
> Tennessee Warbler, 10 on Aug 1. Northern Waterthrush, 2 on Aug 4.
> Clay-colored Sparrow, 3 on Aug 3. LeConte's Sparrows, 4-6 everyday, still
