Mr. J. A. Weber reported one Black-throated Green Warbler 

 {Dendroica virens) and two Blue-headed Vireos (Lanivireo soli-

 season, as follows: Red-shouldered Hawk {Buteo lineatus), 

 April 3, on Staten Island; Barred Owl (Strix varia), April 10, 

 at Newton, N. J.; Robin {Planesticus migratorius) , April 24, 

 at Westfield, N. J. All of the nests contained eggs. Mr. 

 Abbott also reported that Messrs. P. B. Philipp and J. P.
