seen on July 6 and others on July 7 and 8. The first female was seen on 
July 12, and one was found dead on the platform under the light on July 
26. Nine were seen on Little Charity, where it may have bred. 
52. Progne subis subis. Purple Martin. — This species did not breed 
on Charity Island, but a pair was seen on July 6 and several times later. 
They were generally observed flying about over the light-house clearing. 
On July 28, a pair was seen at Little Charity, where there was a martin 
box on top of the fish houses. The birds observed on Charity Island very 
probably came from Little Charity. 
53. Petrochelidon lunifrons lunifrons. Cliff Swallow. — This species 
did not breed on the islands, but two were seen flying about the Charity 
Island Light-House on July 6 and four on July 9 and 10. These were 
seen with flocks of barn swallows that frequently flew about the clearing. 
54. Hirundo erythrogastra. Barn Swallow. — Only one pair of barn 
swallows bred on Charity Island. These started to build in the boat 
house where they were not wanted, and the keepers tore down two partly 
built nests. A nest was then started over the window in the poultry 
house and was completed during the latter part of our stay. The species 
was more common on Little Charity, where it nested in the old houses. 
A flock often came to Charity Island, especially in the morning. 
55. Iridoprocne bicolor. Tree Swallow. — The writer saw single pairs 
of tree swallows on July 6 arid July 10 near the Charity Island Light-House. 
No nests were found, and it rvas not seen often enough to indicate that 
it probably bred here. 
56. Riparia riparia. Bank Swallow. — This species evidently did not 
breed on the islands although there was a high sand bank on the west 
beach of Charity Island. After July 17, the writer saw from four to thirty 
each day, flying and feeding over the clearing on Charity Island. The 
species was not recorded from the islands in 1910, no doubt because it 
had ceased to visit the islands before the date of our arrival (August 16). 
57. Bombycilla cedrorum. Cedar Waxwing. — The cedar waxwing was 
a rather common breeder on Charity Island. A flock was seen on July 7, 
feeding in poplar trees, and several others on later dates and at different 
parts of the island. On July 25, a pair was seen to commence a nest in a 
small willow bush near the garden in the light-house clearing. 
58. Vireosylva olivacea. Red-eyed Vireo. — This species was one of the 
most common breeders on Charity Island and was seen nearly every day 
of our stay. It was observed all over the island, and one nest was found 
at the edge of the light-house clearing. 
59. Dendroica aestiva aestiva. Yellow Warbler. — The yellow warbler 
was first seen on July 20, when three were observed among the willows near 
Light-House Point on Charity Island. No nests were found and no birds 
seen until the above date, and the writer is inclined to consider that the 
ones noted were migrants from the mainland. 
60. Dendroica virens. Black-throated Green Warbler. — This warbler 
did not breed on the islands, but one was seen in the pines near the Charity 
Island clearing on July 27. It was no doubt a migrant from the mainland 
west of the bay, where it is known to breed. 
61. Setophaga ruticilla. Redstart. — The redstart was a not uncommon 
breeder on Charity Island. Adults and young were seen nearly every day 
in July. 
62. Dumetella carolinensis. Catbird. — This species was evidently a 
very uncommon breeder on Charity Island. It was only seen in a willow
