Eggs of the Santa Catalina Partridge 



{Lophortyx catalinensis. Grinnelt) 



THE Santa Catalina Partridge was described in The Auk, Vol. XIII, 

 No. 3, July, 1906, by Mr. Joseph Grinnell. The three eggs figured 

 in our plate are from a set of ten taken July 12th, 1907, at Avalon, 3 an ta 

 Catalina Island, Cal., by P. I. Osburn. Nest on ground near eucalyptus 

 tree and by a fence. A slight depression in ground lined with dry grass. 

 Dry grass eight inches tall surrounded nest and concealed it. Diameter of 

 nest inside, four inches. The clutch consisted of ten eggs slightly incu- 

 bated. The three specimens shown on our plate are a fair representation of 

 all. The eggs are large and handsome, in these respects excelling eggs of 

 any other Partridge. Color almost pure white with few small specks and 

 dots of brown, and large conspicuous yellowish-brown blotches which give 

 the eggs a distinct appearance. They are unlike the eggs of any other North 

 American Partridge. The three specimens which we show are as nearly 

 accurate in size and color as it is possible to get them. The coloring was 

 done by hand by Zoltan de Takach Gyongyoshalaszy. The ten eggs of the 

 clutch measure respectively 1.20 x 1.02 — 1.21 x 1.00 — 1.22 x.97 — 1.21 x 1.00 

 — 1. 17 x .99 — 1. 21 x .98 — 1. 19 x .97 — 1.20 x .98 — 1.22 x .99 — 1.03 x .91.
