Fat loads and flightlessness in Wilson's Phalaropes

Article Abstract:

The fat loads and flightlessness in Wilson's Phalaropes were examined by using a thorough observation of these birds. Results show that the total body mass of shorebird migrants is composed of 45% fat loads. Some adult Wilson's Phalaropes in their late adult stage become to heavy to fly. This condition is caused by a rapid increase in mass gain. However, the greatest rate of fat deposition among Phalaropes is only 60-70% of the theoretical maximum.

Use of ELISA for determination of plasma prolactin levels in the house wren

Article Abstract:

A human prolactin enzyme-linked immunosorbent assay (ELISA) test kit is useful in finding avian prolactin concentrations in the House Wren. Replicate ELISA runs are useful when color intensity decreases over time because of the persistent reaction of sulfuric acid with the substrate chromogen. The sensitivity of the present ELISA is influenced by the fact that it is used against avian instead of human serum prolactin.

Usage, Enzyme-linked immunosorbent assay, Prolactin
