NORTH AMERICAN FAUNA 73 



Wilson's Phalarope (Steganopus tricolor) 



Status: Regular migrant and summer resident, one nest record. 



Migration: Fairly common migrant in the Western Upland, locally common 

 in St. Croix County. Rare and local in the Central Plain and Northern High- 

 land. Spring migrants arrive 20-25 April. Peak abundance occurs 

 10-15 May and departure by 1 June. The first fall migrants arrive 

 20-30 July. Peak abundance occurs 10-25 August and departure by 

 15 September. 



Nesting Season Distribution: I observed an adult male with at least two 

 young that still retained some down feathers on 10 July 1978 in St. Croix 

 County. The wetland where this brood was observed (Sec. 11, T. 29 N., 

 R. 18 W.) occasionally supports breeding plumaged adults during the 

 nesting season in wet years. Numerous nesting season records from this 

 wetland ranging from 9 June (1964) to 17 July (1961) suggest that nesting 

 may have occurred earlier. Summer records from Crex Meadows, Burnett 

 County (26 June 1974 and 27 June 1972), suggest that Wilson's phalarope 

 may also nest at that location. 



Habitat: Wilson's phalaropes use several wetland types during migration, 

 including seasonally and semipermanently flooded wetlands. Summer 

 records are from wetlands where cattail and river bulrush are the predomi- 

 nant vegetation types. 



Northern Phalarope (Lobipes lobatus) 

 Status: Regular migrant. 



Migration: Rare migrant in the Western Upland and at Crex Meadows, Bur- 

 nett County. Casual elsewhere. Spring migrants arrive about 10 May (ear- 

 liest— 30 April 1974 and 1 May 1975, St. Croix County). Northern phala- 

 ropes are most commonly observed during the third week of May and depart 

 by 5 June. Fall migrants arrive in mid- August (earUest— 20 July 1975, St. 

 Croix County) and depart by 15 September. 



Habitat: Northern phalaropes are usually observed on semipermanently and 

 permanently flooded wetlands that have poorly developed shoreUne or emer- 

 gent aquatic vegetation. 



American Woodcock {Scolopax minor) 

 Status: Regular migrant and nesting species. 



Migration: Common migrant throughout the Valley. Spring migrants arrive 

 about 25 March (earliest— 14 March 1951, Polk County and 17 March 1955, 

 Burnett County) and peak abundance occurs 20 April to 1 May. FaU migra- 

 tion begins in mid- August. Peak fall abundance occurs 15 September to 

 1 October and departure by 1 November. 



Nesting Season Distribution: Fairly common and well distributed nesting
