DISCOVERY OF THE 

 NEST AND EGGS OF THE EVENING GROSBEAK 



(Coccothraustes vespertina.) 



BY WALTER E. BRYANT. 



Read June 20, 1887. 



Although this species was first described in 1825, I be- 

 lieve that no description of its nest and eggs has previously 

 appeared. Accordingly I take pleasure in announcing the 

 discovery of the first nest and eggs, by Mr. E. H. Fiske, in 

 Yolo County, California. Eegarding this interesting find- 

 ng, Mr. Fiske has written me the following particulars 

 from his field notes. 



The nest, containing four eggs, was taken May 10th, 1886, 

 but incubation was so far advanced that he was unable to 

 preserve them. In general shape, color and marking, they 

 were similar to eggs of the Black-headed Grosbeak, but in 

 size he thinks they were somewhat larger. 



The nest was built in a small live oak, at a height of ten 

 feet, and was a more pretentious 'structure than is usually 

 built by the Black-headed Grosbeak, being composed of 

 small twigs supporting a thin layer of fibrous bark, and a 

 lining of horse hair. 



It is to be hoped that Mr. Fiske will be successful in find- 

 ing additional specimens from which measurements may b© 

 determined.
