- ECOLOGY OF ISLE ROYALE. 91 



Ave had an opportunity to study the habits of these birds. One was 

 nearly full-grown, while the other three were just getting their wing 

 feathers. All were quite tame and the oldest would eat from the hand 

 and allow itself to be picked up. We were surprised to find how clean 

 these young Gulls were, for the nests were as filthy as those of the 

 domestic Pigeon. They all seem very fond of bathing, and the largest 

 one took a bath several times a day. It A^ould swim out into the bay, 

 splash water over itself with its head and wings, dip its head under 

 water, then shake itself; after repeating these performances several 

 times it would come to the shore, flap the wings and jump as if try- 

 ing to fly. They were very particular about keeping their bills cleau, 

 for after eating they would walk to the water, immerse the bill and 

 shake the head. 



2. Trail to Sislcoirif Lake {Station V, J,). 



This habitat included all the forest along the trail between Siskowit 

 Bay and Siskowit Lake. If it had been in the breeding season it 

 might have been divided into two or three different habitats, but the 

 migrating birds did not seem to show any preference for a particular 

 forest. 



The birds seen at this station were as follows : Golden-croA'STie^l 

 Kinglet, Chickadee, Raven, Pigeon Hawk. Winter Wren, Red-breasted 

 Xutliatch, Bay-breasted Warbler, Red-eyed Vireo, Hairy Woodpecker, 

 Magnolia Warbler, Black-throated Green Warbler, Brown Creeper, 

 White-throated Sparrow, Tennessee Warbler, Flicker, Canada Jay, 

 Junco, Blue Jay, Pileated Woodpecker, Nashville Warbler, Sparrow 

 Hawk, Chipping Sparrow, Grinnell's Water Thrush, Purple Finch, Pine 

 Grosbeak, Sharp-shinned Hawk, Myrtle Warbler, Black-throated Blue 

 Warbler, Olive-backed Thrush, Downy Woodpecker, Yellow-bellied Fly- 

 catcher, and Cape May Warbler. 



The nests of only two birds were found here, the Chickadee and Gold- 

 en-crowned -Kinglet. The Chickadee's nest was in a dead birch tree 

 about ten feet from the ground, and contained four young which were 

 able to leave the nest August 11. The Kinglet's nest was in a spruce 

 tree about thirty feet from the ground. Both old birds were observed 

 carrying insects into the tree, but the top was so thick that the nest 

 could not be seen from the ground. On August 16 the young birds 

 werfe still in the nest. 



The Nashville Warbler, Olive-backed Thrush, Junco, White-throated 

 Sparrow and Chipping Sparrow frequented partial clearings or clear- 

 ings in the breeding season but were found in the forests in the second 

 week in August. On August 11 a flock of birds were seen feeding iu 

 the top of a tall tamarack. They were mistaken for warblers but on 

 shooting one to identify it, it was found to be a Chipping Sparrow. 



3. Siskowit Lake {Station V. 6). 



This Lake was six miles long and about two miles wide at the widest 

 part. The shores were mostly rocky, and trees grew down nearly 

 to the waters edge. The birds found here were : Herring Gull, Osprey, 

 Eagle, Spotted Sandpiper, American JMerganser, Loon, and Kingfisher.
