Family PHALAROPODIDAE, The Phalaropes 

 Lobipes lobatus, Northern Phalarope (223) 



Occasional on plains in migration (Henderson). It was listed for the region 

 by Gale but without data. Apparently common at the Barr Lakes. 



Steganopus tricolor, Wilson's Phalarope (224) 



Summer resident; common in migration and rather infrequent as a summer 

 resident on the Plains. Arrives, May 3-5 (2 records) ; leaves, July 24 — August 3 

 (2 records). Gale found a nest with four eggs on May 31, 1892, near Boulder and 

 also took five sets between May 19 and June 19, 1890, just north of the county near 

 Loveland. 



Family RECURVIROSTRIDAE, The Avocets and Stilts 

 Recurvirostra americana, Avocet (225) 



Migrant; infrequent on lakes in Plains zone. The only definite records for 

 the county: a pair seen May 10, 1888 (Gale) ; a pair seen May 20, 1904 (Rockwell) ; 

 three birds seen August 3, 1912 (the writer). It nests at the Barr Lakes, and Gale 

 collected several sets of eggs just north of the county (May 19 — June 19, 1890). 



Family SCOLOPACIDAE, The Snipes, Sandpipers, etc. 

 Philohela minor, Woodcock (228) 



One was seen near Boulder in 1887 by John Bentley (Cooke), and one by 

 Henderson May 24 and 30, 1905. It is a rare bird in Colorado. 



Gallinago delicata, Wilson's Snipe (230) 



Permanent resident; common as a migrant, less so as a summer resident; 

 infrequent though regular as a winter resident of the Plains. Migrant flocks were 

 noted April 3. A downy young, apparently but a few days old, was noted by the 

 writer June 5, 1910, a few miles east of Boulder. A dead bird, found September 9 

 hanging on a barbed-wire fence, at an elevation of 8,500 feet, is the only record fot 

 the mountains of the county. Widmann, however, saw several near Estes Park 

 at an elevation of 9,000 feet in July, 1910.
