Raptor Nesting Chronology in Northwestern North Dakota
Nesting chronology of raptors is sparsely documented in North Dakota. During 1981-94, we determined hatching dates at 298 nest attempts by eight species of raptors on and within 10 km of Lostwood National Wildlife Refuge, northwestern North Dakota. Mean hatching dates for most common species were 17...
