Observation of nighttime feeding behavior of ducks
A night vision scope was used during 1969-71 to study the nighttime feeding behavior of ducks on prairie wetlands of south-central North Dakota. Adult and immature ducks were observed feeding between 9:00 PM and 4:00 AM, predominantly on midges (Chironomidae) and mayflies (Ephemeroptera). The emergence pattern of these insects appeared to be a major factor influencing duck activity and feeding beh

Hatchability tests with eggs from captive wood ducks
The effect of diet and artificial incubation on fertility and hatchability of wood duck (Aix sponsa) eggs and survival of young was measured. Hatchability of eggs from hens fed a diet containing 37 percent protein was increased significantly (P

Techniques for establishing local breeding populations of wood ducks
A study was conducted on the Arrowwood National Wildlife Refuge in east-central North Dakota to further evaluate a technique for establishing nesting wood ducks (Aix sponsa) by releasing propagated birds and installing nest houses. No wood duck nesting had been recorded previously in the area. During May-July 1968, 253 ducklings, hand-reared at the Northern Prairie Wildlife Research Center near Ja

Effect of certain anesthetic agents on mallard ducks
Four anesthetic agents used in human or veterinary medicine and 3 experimental anesthetic preparations were evaluated for effectiveness in inducing narcosis when administered orally to game-farm mallard ducks (Anas platyrhynchos).Tribromoethanol was the only compound to satisfy criteria of initial tests. Mean duration of the induction, immobilization, and recovery periods was 2.4 minutes, 8.7 minu

Production and standing crop of Hexagenia (Ephemeroptera) in a large reservoir
Population dynamics of the mayflies, Hexagenia limbata (Serville) and Hexagenia bilineata (Say), were studied in Lewis and Clark Lake from 1962 to 1969. Nymphs that hatched in June and July emerged as adults in 13-14 months (titled 1-year cycle) and nymphs hatched in late August or September emerged in 22 months (titled 2-year cycle). Although an estimated 79% of the newborn nymphs begin life in t
