To determine cause of death of Florida sandhill crane (Grus canadensis pratensis) chicks, in 1996-99 we glued shorttenn transmitters on newly hatched chicks. At about 10 days of age, these were replaced with surgically implanted subcutaneous transmitters in the field. Chicks were then recaptured at 55 to 65 days of age for more pennanent transmitters. This combination of transmitter configurations allowed us to track individuals through their rapid-growth period.
