,YA{\ Wright, Morning Awakening and Evensong, [ol-u 



record of L913 be excepted, it is but eleven minutes in the sixteen 

 evenings. The difference in the amount of the Robin's even-song 

 is very wide. On one occasion there was no song the entire time of 

 the record which began at 6.30, ami only infrequently was a eall 

 heard. During the time of even song on several occasions Robins 

 have sung but little, voicing themselves intermittently only, 

 which is very unlike their jubilant ami continuous singing for forty 

 or forty-five minutes in the morning awakening. On the other 

 hand occasionally one of the Robins of the neighborhood becomes 

 a very free singer in the evening. 



Nineteen records of Veery average 35 minutes after sunset ami 

 8.03 for (.'alls as well as song. The latest record for the song is 40 

 minutes at 8.08 on -Inly 8. 1913; there is a similar record for the 

 eall on -Tune 10 at 8.05, 40 minutes. The variation in time of last 

 song is fifteen minutes, but on fourteen of the evenings is but three 

 minutes, constituting the Veery one of the most regular of all the 

 speeies in retiring to rest. 



Thirty-two records of Olive-backed Thrush average '-I7 minutes 

 after sunset and 8.05 for the song; for calls one minute later. The 

 latest i.< 49 minutes at S.10 on June 4. 1913, for the song. Four 

 other records for the song are just earlier, at 41 and 42 minutes. 

 The variation in time of last song on twenty-seven occasions is 

 lnit seven minutes, constituting the Olive-backed Thrush as well 

 as the Veery one of the most regular of all the speeies in its final 

 song before rest. 



These speeies were only casually recorded: Sharp-shinned Hawk 

 \Accipitcr velox) pursued by a pair of Tree Swallows. 7.21 ; Barred 

 Owl (Strix varia varia), 7.40; Northern Flicker (Colaptes auraius 

 luteus), 7. IS; Whip-poor-will (Antrostomus vociferus vodferus) 

 singing from 7.2S to 7A^; Nighthawk (ChordeUes virginianus 

 rirginianus), 7.32 to 7.34; Ruby -throated Hummingbird (ArcM- 

 lockus colubris), 7.20 to 7.42 o'eloek. The Hummingbirds visited 

 an apple-tree in blossom in the evening of May 31, 1913. One of 

 the pair was seen hovering over the flowers at 7.20; the second 

 appeared five minutes later, and the two together were busily en- 

 gaged sipping and humming for four or five minutes, when one flew 

 away and the other remained until 7.42, or 24 minutes after sunset, 

 at which time the light had become rather dim.
