The following table gives a summary of the previously published notes:

It seems very desirable to have some observations made during the migrat- 

 ing season in order to establish records of the species that use these keys as 

 stepping-stones in their journey to and from the West Indian Islands and 

 the mainland beyond. 



May 15, Miami: Red-bellied woodpecker (mating), mocking-birds, purple 

 martins, boat-tailed grackles. 



May 16, Miami: About the harbor we noticed 4 laughing gulls, a least 

 tern, 8 man-of-war birds, and 3 brown pelicans. The laughing gulls con- 

 sisted of adult and immature individuals. 



Second Ragged Key north of Sands Key: Here we noted 2 green herons, 

 a Florida yellowthroat, and many redstarts, both male and female. They 

 were all fluffed up, as they usually are after a long journey. They probably 

 arrived very recently. One wonders if it is the long journey or the lack of 

 fresh water on these islands that gives to these migrant birds the peculiar 

 puffed-up, fluffy appearance, characteristic of all the migrating birds observed 

 on these keys. 



First Ragged Key north of Sands Key: Redstarts in abundance, and a 

 few Florida yellowthroats. 



Sands Key: The absence of mosquitoes, owing to the lack of rain, made a 

 thorough exploration of Sands Key possible, but the effort revealed few birds. 

 Redstarts everywhere, a few Florida yellowthroats, 2 Florida cardinals, and 

 2 Key West vireos constituted our whole list. 



We returned to our landing in the Miami River after sundown. The 

 bright moonlight stimulated the mocking-birds to outdo themselves in song. 

 In this they were joined by a chuck-will's widow, whose measured notes 

 came to us from the farther bank of the river. 



May 17: In a trip taken through Brickie's Hammock this morning, the 

 following birds were seen: Boat-tailed grackles, Florida cardinals, Florida 

 blue jays, gray kingbirds, ground doves, and mocking-birds. 



In the afternoon we visited Mr. Simpson's place, "The Sentinels," on 

 Little Rivers, where the following birds were seen: several Florida cardinals, 

 a lot of boat-tailed grackles, a pair of Key West vireos, Florida blue jays, 

 Florida yellowthroats, ground doves, yellow-billed cuckoos, mocking-birds, 

 and an Everglade kite flying over the mangrove thickets fringing the bay, 

 the first which I have seen for a long time. 



In Biscayne Bay we saw laughing gulls, least terns, and man-of-war birds. 



May 18: Visited Cape Florida, where we saw a few royal terns on the 

 stakes marking the channel, 8 Florida cormorants on a piece of driftwood, 

 a man-of-war bird, several Florida cardinals, and a pair of gray kingbirds. 



May 19: In sailing down Hawk Channel between Cape Florida and 

 Indian Key, only a few laughing gulls and 2 man-of-war birds were seen. 



Indian Key: We saw 3 laughing gulls, least terns, a turkey buzzard, man- 

 of-war birds, 2 red-belHed woodpeckers, and a nesting colony of boat-tailed 

 grackles.
