ECOLOGY OF ISLE ROYALE. 369 



71. Melospisa georgiana (584). Swamp Sparro-n-. 



Range: Eastern North America to the Plains, accidently to Utah, 

 north to the British Provinces, including Newfoundland and Labrador. 

 Breeds from the Northern States northward, and winters from Massa- 

 chu:setts southward to the Guljf States. 



Stations: Eock Harbor, Bulrush Zone and Delta, III, 3; III, 5. 



Breeding: Adults accompanied by one young seen July 26. 



Several of these birds were heard singing at the mouth of a little 

 stream near the west end of Rock Harbor (III, 3). This was an ideal 

 spot for this species as the stream was slow and deep, with grassy bogs 

 and alder bushes along its banks. Others were noted on a grassy bog 

 around Sumner Lake (III, 5). The single immature specimen observed 

 was found at the west end of Eock Harbor, July 26. 



72. Petrochelidon. Itinifrons {Q12) . Cliff Swallow. 



Range: North America north to the limit of trees, breeding south 

 to the valleys of the Potomac and the Ohio, southern Texas, southern 

 Arizona, and California; Central and South America in winter. Not 

 recorded from Florida or the West Indies. 



Stations : Rock Harbor, Scovill Point, IV, 1. 



Breeding : Occupied nests July 19. 



The Cliff Swallow was only found at one place on the island and 

 only several pairs were seen here. 



Breeding Notes: At Scovill Point (IV, 1) on July 19 a number of 

 Cliff Swallows' nests were found placed on the bare face of the rocks. 

 They were above the reach of the waves and were usually protected above 

 by shelving of rock. The nest was composed of mud and lined wath 

 feathers but could not be examined closely. The probabilities are that 

 they contained young, as the old birds continually flew to the nest and 

 then away again, chattering all the time. 



73. Hirundo erythrogaster (613). Barn Swallow. 



Range: North America in general, breeding from the Fur Countries 

 south into Mexico; visits the West Indies in migrations, and winters in 

 Central America and South America. 



Stations: Rock Harbor, Spruce and Balsam Forest, I, 2-3. Men- 

 agerie Island, V, 10. 



Breeding: August 17, nest with young. 



On July 9 a flock of these swallows stayed around the light-house 

 and neighboring islands for some time and finally flew away toward 

 the south. 



Breeding Notes: At Menagerie Island we saw four nests in a small 

 boat-house, on August 6. Several pairs of adults were flying about the 

 buildings. On August 17 they were again seen and a fifth nest contain- 

 ing young was found, this time built against the bare cliff about twenty 

 feet above the waves. A shelving of rock a few feet above protected it 

 from the rain. This nest contained four young nearly able to fly. An 

 old nest was placed a little ways from this one and in a like location. 



74. Iridoprocne bicolor (614). Tree Swallow. 



Range: North America at large, breeding from the Fur Countries 

 south to New Jersey, the Ohio Valley, Kansas, ^and Colorado, etc., winter- 

 ing from South Carolina and the Gulf States southward to the West 

 Indies and Guatemala.
