A BIRD CALENDAR 



Robins also begin to lay. Notable arrivals are the Hermit Thrush, 

 Sapsucker, and the first straggling swallows — Tree, Bank and 

 Bam. 



April {late). Hairy Woodpecker, White-breasted Nuthatch 

 and Song Sparrow lay, and quite a number of birds arrive — ^all 

 the swallows, the herons, Whippoorwill, Chimney Swift, Towhee, 

 Brown Thrasher, Chebec, and a few warblers, such as Black- 

 throated Green, Black and White, and Oven-bird. 



May {first third). During this time the following hawks lay 

 their eggs, usually finishing by the 10th: Fish, Cooper's, Marsh, 

 Sparrow, and Broad-winged, the latter sometimes later. Night 

 Heron colonies have eggs early in the month. Blue Jay, King- 

 fisher, Vesper Sparrow, Grackles, Wood Duck and Ruffed Grouse 

 lay — the latter sometimes earlier and later, and the Wood Duck 

 sometimes earlier. In this period the great majority of our smaller 

 birds not already mentioned begin to appear. The migration of 

 aU the warblers is in full progress by about the 10th. Homed 

 and Pied-billed Grebes appear in the ponds or streams. Most 

 of our small summer-resident birds arrive. 



Mat {second third). The following lay their eggs: Swamp, 

 Field, Chipping and Savanna Sparrows, Meadowlark, Phoebe, 

 Bam Swallow, Green Heron, Louisiana Water Thrush, Sharp- 

 shinned Hawk. By this time all summer residents have arrived. 

 The migration of shore-birds is at its height, especially, of course, 

 in evidence along the coast, and likewise of the warblers and 

 small land-birds in general. At this time there are more kinds 

 and larger numbers of birds to be seen than at any other time of 

 year. This is the time of times to detect rarities, and the bird- 

 lover might well wish to be afield every minute and to be multiplied 

 a thousand-fold. 



Mat {last third). Another contingent are now busy laying: 

 Downy Woodpecker, Flicker, Chickadee, Purple Finch, Brown 

 Thrasher, Wood Thrush, Chewink, Veery, Spotted Sandpiper, 

 Oven-bird, and early individuals of any of the warblers. The 

 migrants are disappearing, the last being the BlackpoU Warbler 

 in the early days of June. 



June. By the first few days of the month nearly all the small
