Gas-liquid chromatographic determination of kepone in field-collected avian tissues and eggs Gas-liquid chromatographic determination of kepone in field-collected avian tissues and eggs
A procedure is described for determining Kepone (decachlorooctahydro-l,3,4-metheno-2H-cyclobuta [cd]pentalene-2-one) residues in avian egg, liver, and tissue. Samples were extracted with benzene-isopropanol, and the extract was cleaned up with fuming H2SO4-concentrated H2SO4. Kepone was separated from organochlorine pesticides and polychlorinated biphenyls on a Florisil column and...

Observations and reinterpretation of kingfisher-raptor interactions Observations and reinterpretation of kingfisher-raptor interactions
Reported observations of Belted Kingfisher (Megaceryle alcyon)-raptor interactions have ranged from brief encounters where the kingfisher escaped the raptor and the hawk subsequently flew away to repeated chases (Johnson 1925, McCabe and McCabe 1928, Skinner 1928, Smith 1963). In some repetitive chases, kingfishers appeared to initiate the interaction (McCabe and McCabe 1928, Skinner...

Howling at two Minnesota wolf pack summer homesites Howling at two Minnesota wolf pack summer homesites
Howling sessions were monitored at two Minnesota wolf pack homesites for 2255 h between 29 April and 3 August 1973. All sessions recorded occurred from dusk through early morning, with an evening peak for one pack. Within a night, multiple sessions were grouped temporally, most occurring within an hour of one another. Howling rates for both packs increased throughout the homesite season...

Effects of dietary vanadium in mallard ducks Effects of dietary vanadium in mallard ducks
Adult mallard ducks fed 0, 1, 10, or 100 ppm vanadyl sulfate in the diet were sacrificed after 12 wk on treatment; tissues were analyzed for vanadium. No birds died during the study and body weights did not change. Vanadium accumulated to higher concentrations in the bone and liver than in other tissues. Concentrations in bones of hens were five times those in bones of drakes, suggesting...

Artificial insemination for breeding non-domestic birds Artificial insemination for breeding non-domestic birds
Captive breeding of non-domestic birds has increased dramatically in this century, and production of young often exceeds that of the same number of birds in their native habitat. However, when infertility is a problem, artificial insemination can be a useful method to improve production. Artificial insemination programs with non-domestic birds are relatively recent, but several notable...

Indocyanine green: A test of hepatic function and a measure of plasma volume in the duck Indocyanine green: A test of hepatic function and a measure of plasma volume in the duck
1. The exponential removal of ICG from the plasma by the mallard duck liver made possible the measurement of fractional dye clearance (K), plasma volume (PV) and plasma clearance (PC). 2. Values obtained for K (14.9%/min), PV (39.2 ml/kg) and PC (5.8 ml/min per kg) agreed with those obtained by other techniques used in a number of species. 3. Sex did not affect the removal of ICG by the...
