Use of monoclonal antibodies developed against chicken coccidia (Eimeria) to study invasion and development of Eimeria reichenowi in Florida sandhill cranes (Grus canadensis) Use of monoclonal antibodies developed against chicken coccidia (Eimeria) to study invasion and development of Eimeria reichenowi in Florida sandhill cranes (Grus canadensis)
Eimeria gruis and Eimeria reichenowi are common coccidial parasites of a number of species of cranes. Until recently, little was known about either the site for invasion or the dynamics of early development of the crane coccidia because of the difficulty of identifying sporozoites and early developmental stages of these parasites by conventional staining methods. In the present study...

The effect of chemical weapons incineration on the survival rates of Red-tailed Tropicbirds The effect of chemical weapons incineration on the survival rates of Red-tailed Tropicbirds
In 1992, the Johnston Atoll Chemical Agent Disposal System (JACADS) began incinerating U.S. chemical weapons stockpiles on Johnston Atoll (Pacific Ocean) where about 500,000 seabirds breed, including Red-tailed Tropicbirds (Phaethon rubricauda). We hypothesized that survival rates of birds were lower in those nesting downwind of the incinerator smokestack compared to those upwind, and...

Recommendations for the attachment of satellite transmitters to cranes Recommendations for the attachment of satellite transmitters to cranes
Recent advances in miniaturization of satellite transmitters have resulted in thumb-sized packages weighing less than 30 g. These are smaller than VHF radios routinely mounted on crane leg bands. With this development and with favorable signal reception results, there is no need for, and much to recommend against the continued use of back-pack mounts. We provide details for leg-mount

Ingested metal in whooping cranes: An endoscopic technique for removal and implications for the release program Ingested metal in whooping cranes: An endoscopic technique for removal and implications for the release program
Since 1993 when the whooping crane (Grus americana) release program in Florida started, 21 whooping cranes at the USGS Patuxent Wildlife Research Center (Patuxent) have been diagnosed with gastrointestinal foreign bodies (primarily metal objects). A technique for safely removing these objects has been developed. The technique uses a flexible gastric endoscope to enter the proventriculus...

A comparison of behavior for two cohorts of captive-reared greater sandhill cranes released in northern Arizona A comparison of behavior for two cohorts of captive-reared greater sandhill cranes released in northern Arizona
To determine how the behavior of greater sandhill cranes (Grus canadensis tabida) changes according to time of year, time of day, and number of days after release, we observed the activities of 2 groups of captive-reared greater sandhill cranes at Mormon Lake, northern Arizona. The behaviors we compared were alert, loafing, sleeping, foraging, preening, locomotion, and other. We found...
