141. (678) Oporornis agilis. CoNNrEctTICUT \WARBLER—This spe- 
cies was first seen on the morning of August 31, near the path 
across the island. The preceding night had been clear and cool, 
with a strong northeast wind. ‘The species arrived with the oven- 
bird and mourning warbler, remained fairly common until Sep- 
tember 9, and was seen as late as September 19. It was only ob- 
served in the interior of the island, where it fed under tall ferns 
that grew in profusion there. By walking quietly and slowly and 
stopping to call, birds of this species, if within hearing, would usu- 
ally hop or fly up into the low branches of trees or on logs. They 
would come quite close to the observer, but generally disappeared 
promptly when they got a good look at the intruder. Some were 
called out of low thickets, but most of them seemed to feed in the 
thick ferns in the more open places in the woods. 
142. (685) Wilsonia pusilla pusilla. Witson’s WARBLER.—The 
first bird of this species was seen on September 7, when the writer 
secured one in the poplar trees near the path across the island. 
This.was the only one seen in the interior, but a few hours later 
another was seen in a low maple near the beach at the south end 
of the island. 
148. (686) Wilsonia canadensis. CANADA WaARBLER.—On August 
27, several Canadian warblers were seen in low willow bushes on 
the first sand dune on the west side of the island. It was not 
noted again until September 8 and 9, and other records were se- 
cured on September 138 and 15. At Ann Arbor, the species has 
been seen as early as August 28 (1908), and at Point Pelee on 
August 15 and 16 (1908). 
144. (687) Setophaga ruticilla. Repsrart.—This species was a 
not uncommon breeder on the island. On the night of Septem- 
ber 4, numbers came with the migration of warblers, thrushes and 
vireos, but by September 10 none could be found. On September 
13, a few more came and were seen almost daily until the night of 
October 5, when their number was increased by hundreds that ar- 
rived with the migration of palm and myrtle warblers. ‘The red- 
starts all disappeared on the next night, and no more were seen 
on the island. 
145. (697) Anthus rubescens. Preir—WHarly on the morning of 
September 19, the writer observed a flock of about twenty of this 
species on the west beach. The birds were walking about and 
feeding among the rocks. This flock was very wild, and when dis- 
turbed flew off toward Sand Point. No more were seen until Sep- 
tember 23, when a flock of fifteen came to the light-house beach. 
This flock was increased to about fifty the next day, but these 
passed on during the next few days, and on September 27 but one
