288 Felger, Colorado Water Birds. [jjg 



records one that Dr. W. H. Bergtold saw in Denver in June, 1895; also a 

 pair with three young found July 3, 1897, at Timnath, Larimer County, 

 some two or three miles west of this area. (Birds of Colo., pp. 64, 158.) 

 Judge Junius Henderson writes that on May 24 and also on May 30, 1904, 

 he saw one of tins species, presumably the same bird, one mile east of 

 Boulder. 



230. Gallinago delicata. Wilson's Snipe. — "Winter resident. (Sept. 

 26-about May 1.) In migration, common; in winter, rather rare except 

 in certain localities, such as the vicinity of warm springs along the Platte 

 River, where one may expect to see a few of them all through the winter. 



232. Macrorhamphus scolopaceus. Long-billed Dowitcher. — Mi- 

 grant; not uncommon. (Last week in April-?; July 24-Sept. 30.) Mr. 

 H. W. Hejishaw's capture, near Denver, of a bird of this sepcies on 

 July 24, 1873, makes one wonder whether it may not be some day found 

 breeding here. My own latest spring record is May 13. 



233. Micropalama himantopus. Stilt Sandpiper. — Migrant; not 

 common. (May-early June; latter part of July-Sept. 30.) I do not 

 believe tins bird to be as rare as appears from previous reports. It occurs 

 regularly in small numbers along the Barr Lake Chain and I would not 

 expect a season of systematic note-taking there to pass without seeing a 

 few of them, or possibly several small flocks. It starts south early, in the 

 latter part of July, and from my experience it is more common in fall than 

 in spring migration. 



239. Pisobia maculata. Pectoral Sandpiper. — Migrant ; common. 

 (First part of May-first part of June; latter part of July-Oct. 7.) Begins 

 to return early, along with other species of sandpipers, in latter part of 

 July. 



[240. Pisobia fuscicollis. White-rumped Sandpiper. — Migrant; rare 

 in adjoining area. Cooke states that it is "not uncommon" in the State, 

 "finding its western limit at the base of the Rockies," and "reported by 

 Osburn," presumably from Loveland. (Birds of Colo., p. 55.)] 



241. Pisobia bairdi. Baird's Sandpiper. — Migrant, or summer resi- 

 dent. (April-Oct. 3.) The most abundant of our sandpipers and espe- 

 cially numerous during the late summer and fall. I have found them 

 in the middle of June and through July in flocks ranging from twenty-five 

 in the middle of June to two hundred or more by the end of the first week 

 in July. The most of these flocks are wild and restless, as birds will be in 

 migratory flight, flushing at 100-150 yards, swishing round and round, 

 then many times towering high into the air and striking out to the south 

 or southeast. Many of the members of these early flocks appear to be 

 young. Some during these early summer periods are found also in ones, 

 or twos, and while it is, I think, not known to breed this far south, these 

 data force one to question whether it does not breed here or in the near-by 

 mountains. This is my only excuse for adding, "or summer resident" 

 after "migrant." 



242. Pisobia minutilla. Least Sandpiper. — Migrant, or summer
