Nonparental Attendants in a North-Temperate Migrant
Nonparental attendants (NPAs) are recorded in 46 of the 304 (15%) North American passerines. With a few well-studied exceptions, accounts are often anecdotal especially for migratory species. The authors observed juvenile and adult NPAs in a migratory population of the Grasshopper Sparrow (Ammodramu...

| description | Nonparental attendants (NPAs) are recorded in 46 of the 304 (15%) North American passerines. With a few well-studied exceptions, accounts are often anecdotal especially for migratory species. The authors observed juvenile and adult NPAs in a migratory population of the Grasshopper Sparrow (Ammodramus savannarum ), a small emberizine (17 g) that is a common summer resident of North American grasslands. Nests did not differ significantly in young fledged with and without NPAs. The authors suggest that the NPAs are likely a case of misdirected parental care. |
