Cassinia, Vol. 15, 1911, by the Dela- 

 ware Valley Ornithological Club. 



Cassinia for 1911 comes to hand just 

 as good as ever. It is one of the stand- 

 ard bird publications of the country

 that puts it out. It contains the fol- 

 lowing articles of general interest:

Disappointed. 

 A. M. Abbott and E. R. Ford spent 

 a day in early April with us in an en- 

 deavor to locate nests of the Horned 

 and Barred Owl. We are sorry to say 

 that they failed. Come again, boys, 

 with better luck. 



Goose News. 



At the present writing we have one 

 Canada goose sitting on six eggs with 

 every prospect of bringing off the 

 young. Our Bean goose made a nest, 

 laid two eggs and abandoned them 

 for some reason or other. We have a 

 number of pairs of White-fronted, 

 Snow Geese, Ross's Geese, Cackling 

 Geese, Hutchins' Geese.and Blue Geese 

 mated at this writing (Apr. 29), though 

 none of them have as yet selected 

 nesting sites or laid eggs. 



Some rather unusual combinations 

 are a Cackling goose and a Barnacle 

 gander, a Ross's goose and a Hutchins' 

 gander, and a Lesser Snow goose and 

 a Blue gander all mated up. We are 

 watching them with much interest to 

 see what these combinations will re- 

 sult in. 



California Condor's Egg. 



While at San Diego, March 25th we 

 purchased the collection of eggs for- 

 merly belonging to J. H. McConville, 

 an old San Diego collector, but which 

 for a number of years had belonged 

 to Dr. C. C. Valle, and has been on ex- 

 hibition in the Chamber of Commerce 

 building in that city. 



This collection of eggs contained 

 one of the best known and certainly 

 one of the best prepared specimens of 

 the eggs of the California Condor 

 (Gymnogyps calif ornianus) in exist- 

 ance. This egg was fresh when taken 

 and was blown with a No. 2 drill. An 

 account of the taking of this egg was 

 published in The Condor, Volume 11, 

 page 124-6. 



In securing it we have made a val- 

 uable addition to our collection. 



Bobolink Data 



(Bolichonyx oryzivorus) 

 There is no time during the year 

 that I await more eagerly than the 

 fifteenth day of May, for that date
