ever heard anything like it." 



There are cultivated fields and dyked meadows 

 at Advocate, but behind and on both sides back 

 from the sea, the country is heavily forested, for 

 the most part with red spruce and balsam fir, 

 white and yellow birches. White spruces are 

 common near the sea. The black spruce and 

 sweet birch are rare and the gray birch, iarch and 

 mountain ash are not uncommon. Sugar maples 

 and ashes are also found. The region is more 

 boreal than the Annapolis valley through which 

 we passed, where red oaks, white and red pines, 

 hemlock and beeches are common. Birds of the 

 Transition Zone seen in the latter region and not 

 encountered in Advocate were: Wood Peewee, 

 Least Flycatcher, Chestnut-sided Warbler, Cat- 

 bird, Veery and Bluebird. 



In the following list of eighty-one species, all, with 

 the exception of the Loon, Double-crested Cor- 

 morant, Great Blue Heron and Least Sandpiper, 

 were breeding in this region, and it is possible 

 that these may breed there. In the previous 

 summer I found evidence of the Least Sandpiper 

 breeding farther south at Cape Sable Island. 



1 Loon: Gavia immer. Few. 



2 Black Guillemot: Cepphus grylle. Eight 

 or ten pairs breeding in the cliflfs of Isle Haute. 



3 Great Black-backed Gull: Larus marinus. 

 Although I did not find their nests, I believe that 

 several pairs bred at Isle Haute. 



4 Herring Gull: Larus argentatus. About five 

 hundred pairs, possibly more, nested on the cliffs 

 of Isle Haute and especially on the steep turf-clad 

 portion of the western side. Here the nests were, 

 for the most part, in depressions of the turf and 

 destitute of nesting material. On July 12 most 

 of the young were out of the eggs and running 

 widely on the turf, but confined within narrow 

 limits on the ledges of the cliffs. 



5. Double-crested Cormorant: Phalacroco- 

 rax a. auritus). Two or three seen. 



6. Red-breasted Merganser : Mergus serra- 

 tor. A pair nesting near the salt pond at Isle 

 Haute. 



7. Eider: Somateria mollissima dresseri. Six 

 or seven pairs nesting at Isle Haute. On July 

 14 a pair seen, the male in full nuptial plumage. 

 On July 16 a nest with four eggs was shown me 

 by the light-house keeper under a spruce bush on 

 the cliff about fifty feet up. On the same day a 

 flock of fourteen were seen, all in brown dress 

 but two, that were only partially moulted into 

 the eclipse plumage. 



8. Great Blue Heron: Ardea herodias. One 

 seen. 



9. Least Sandpiper: Pisobia minutila. A 

 few migrating flocks. 



10. Spotted Sandpiper: Actitis macularius. 

 Common. 



11. Semipalmated Plover: Aegialitis semi- 

 palmata. On July 1, two pairs plainly showed by 

 their actions that they had eggs or young on the 

 sandy and pebbly bay of Advocate Harbor.

12. Canada Ruffed Grouse: Bonasa um- 

 bellus togata. Common. 



13. Broad- WINGED Hawk: Buteo platypterus. 

 One seen on June 28. 



14. OSPREY: Pandion haliaetus carolinensis. 

 Two seen. 



15. Great Horned Owl: Bubo v. virginianus. 

 On June 29, three young, fully grown and able to 

 fly, but with heads still in the down and with 

 downy ear tufts were seen in spruce woods. One 

 called repeatedly a plaintive note ee-ah. 



16. Belted Kingfisher: Ceryle alcyon. Few 

 seen . 



17. Hairy Woodpecker: Dryobates v. villosus. 

 Few seen. 



18. Downy Woodpecker: D. pubescens media- 

 nus. Few seen. 



19. Arctic Three-toed Woodpecker: Pico- 

 ides arcticus. One seen on July 1. 



20. Northern Flicker: Colaptes auratus lu- 

 teus. Common. 



21. Chimney Swift: Chaetura pelagica. A 

 few. A pair was found nesting in a fish house at 

 Refugee Cove. The nest was attached to a piece 

 of canvas nailed to the logs of the wall near the 

 roof, and the birds entered through a stove pipe 

 hole in the roof. There were five eggs on July 9. 



22. Ruby-throated Hummingbird: Archilo- 

 chus colubris. A few. 



23. Kingbird: Tyrannus tyrannus.^ Uncom- 

 mon. 



24. Olive-sided Flycatcher: Nuttallornis 

 borealis. Not uncommon. 



25. Yellow-bellied Flycatcher: Empidonax 

 flaviventris. Common. On July 5, I found a 

 nest between two moss-covered logs on the ground 

 containing several black, downy young. 



26. Alder Flycatcher: E. trailli alnorum. 

 Uncommon. 



27. Canada Jay: Perisoreus c. canadensis. 

 One seen. 



28. Northern Raven: Corvus corax princi- 

 palis. Common. A family group of four or 

 five at Refugee Cove and another at Isle Haute. 

 At the latter place they undoubtedly preyed on 

 the eggs and young of the Herring Gull. 



29. Crow: Corvus b. brachyrhynchos. Com- 

 mon. 



30. Bobolink: Dolichonyx oryzivorus. Few.
