Iridoprocne bicolor. — Tree Swallow. In the little marsh back of the 

 hotel at Beaumaris we saw one flying over the water on August 29.

 where — we found it present on all the islands visited, on the main- 

 land, etc. 



Vireo olivaceus. — Red-eyed Vireo. A common tipecies on the isl-

Mniotilta varia. — Black and White Warbler. Fairly common in 

 all parts of Gibralter Island.

 ly common, on August 28 and 29 we saw two on each day and one on 

 August 31 and September 1.

 so seen thi'oughoyt our stay on the island, several seen August 29 

 on the mainland.

 male, taken in the pines directly back of our cabin. 



Dendroica maculosa. — Magnolia Warbler. But three birds found —

 three seen August 29, a few individuals at different times during our

 date we failed to find it. A common breeder here. 



Dendroica vigorsii. — Pine Warbler. Rather common until Septem- 

 ber 1st. we did not find it later.

 part of the island on August 29th we flushed one bird. Is a common 

 summer resident.
