Hematological and serum chemistry norms for sandhill and whooping cranes Hematological and serum chemistry norms for sandhill and whooping cranes
The normal values used as a diagnostic tool and for comparison of cranes were established in the early 1970's. In that early study, no effort was made to look at factors such as age, sex, or subspecies. In addition, during the early study disease problems (primarily disseminated visceral coccidiosis) and nutritional problems were undiagnosed and uncontrolled. For 2 years during the...

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...

Lessons from the motorized migrations Lessons from the motorized migrations
Ten experiments have been conducted to determine if cranes can be led on migration and if those so trained will repeat migrations on their own. Results have been mixed as we have experienced the mishaps common to pilot studies. Nevertheless, we have learned many valuable lessons. Chief among these are that cranes can be led long distances behind motorized craft (air and ground), and...

Methods for estimating dispersal probabilities and related parameters using marked animals Methods for estimating dispersal probabilities and related parameters using marked animals
Deriving valid inferences about the causes and consequences of dispersal from empirical studies depends largely on our ability reliably to estimate parameters associated with dispersal. Here, we present a review of the methods available for estimating dispersal and related parameters using marked individuals. We emphasize methods that place dispersal in a probabilistic framework. In this

Minimum survival rates for Mississippi sandhill cranes: a comparison of hand-rearing and parent-rearing Minimum survival rates for Mississippi sandhill cranes: a comparison of hand-rearing and parent-rearing
Hand-reared (56) and parent-reared (76) juvenile Mississippi sandhill cranes (Grus canadensis pulla) were produced at the Patuxent Wildlife Research Center (Patuxent), Laurel, Maryland over a 4-year period (1989-92) and released at the Mississippi Sandhill Crane National Wildlife Refuge (Refuge), Gautier, Mississippi in a controlled experiment. Hand-reared survival rates proved higher...
