116 MICHIGAN SURVEY, 1908. 



3. Blunders and Fatalities. A comparatively new danger which 

 besets migratory birds on the island is the fatal attraction of the lighted 

 windows of resorts and the light-houses. During the migration scores 

 of warblers, chiefly Tennessee and Palm, killed themselves by striking 

 against the lighted windows of the Club-house which stood in a clearing 

 near the Harbor. Many also met death by the same means at Washing- 

 ton Island, which is situated at the entrance to the harbor. Among 

 the species killed at the latter place were the Tennessee, Blackpoll, 

 Myrtle, Magnolia and Palm Warblers, Gray-cheeked, Olive-backed and 

 Hermit Thrushes, and several species of sparrows. On September 2, 

 during a hard storm which lasted several days, five Olive-backed 

 Thrushes were found dead by Wood beneath the windows at the hotel, 

 and on September 5, a Gray-cheeked Thrush was found dead at the 

 same place. This latter was the first one of this species seen, no other 

 being observed until September 12. All the birds were killed on the 

 north side of the buildings. Sometimes after cloudy nights numbers 

 of small birds would be found on the north porch of the Club-house in a 

 dazed condition, probably from striking the building, the night before. 

 Both young and adults were found, the young being the only ones 

 killed on , clear nights. 



The light-house keeper at Menagerie Island in Siskowit Bay, Mr. J. 

 H. Malone, reported that hundreds of birds lost their lives every spring 

 and fall at his light alone. It was mainly on cloudy nights that the 

 birds struck the lighted windows and the lantern, but some were killed 

 on other nights.
