66 J. A. ALLEN, CATALOGUE OF 



arriving about the second week of May ; leaves last of Au- 

 gust. Arrives the latest, and leaves the earliest, of the 

 Swallows. Breeds in communities. 



86. Progne purpurea Boie. Purple Martin. Not a- 

 bundant. Arrives early in May ; leaves last of August. 



All the Hirundines are gregarious during the latter part 

 of summer, and at other times as much so as the duties of 

 incubation will admit. 



87. Ampelis garrulity Linn. Bohemian Wax-wing. 

 Winter visitant. Accidental. One was taken a few years 

 since a few miles south of this city. (East Windsor Hill, 

 Ct Dr. W. Wood.) 



88. Ampdis cedrorum Baird. Cedar Bird. Cherry 

 Bird. " Wax-wing." Abundant during the summer. Is 

 quite irregular and roving in its habits ; seen here at near- 

 ly all seasons. Seems to be influenced in its wanderings 

 by the supply of food rather than by climate, having ob- 

 served it in Cambridge in every winter month, where it is 

 often excessively abundant in February and March, feed- 

 ing on cedar, ash, and hawthorn berries. Are also found 

 in winter along the south side of Mount Holyoke. (C. W. 

 Bennett.) Have observed them often in February and 

 March at Springfield, but they are not common settled vis- 

 itors till late in May. Seldom begins nesting before the 

 15th or 20th of June, often laying its first eggs as late as 

 the 25th ; have seen the young of the second brood scarcely 

 fledged September 12th. In May they gorge themselves 

 to excess with the petals and stamens of apple blossoms, 

 and generally depend on the smaller fruits for sustenance ; 

 they also take many insects, darting from a perch upon 

 them, like the Flycatchers, and towards the end of summer 

 hunt them in the air for half an hour together, pursuing 

 them like the Swallows, but more clumsily, and apparently 

 for amusement rather than from necessity. Gregarious at 

 all seasons, but seen in smaller parties while breeding. 



89. Collyrio borealis Baird. Great Northern Shrike. 

 Butcher Bird. Regular winter visitant, but not very com- 

 mon. Seen from last of October to middle of April. 



90. Vireo (Vireosylvia) olivaceus Yieill. Red-eyed 

 Vireo. Abundant, breeding in open woods everywhere, 

 generally fixing its nest to bushes and saplings, four to
