Title: Use of a fiberscope for examining cavity nests

Author: Purcell, Kathryn L.;

Date: 1997

Source: Journal of Field Ornithology 68:283-286

Publication Series: Scientific Journal (JRNL)

Description: A system is described that uses a fiberscope to view nests in cavities to provide detailed information on eggs and nestlings. The flexible probe can be inserted around bends, and the tip articulates to allow viewing of the entire cavity and nest. A light guide bundle furnishes light to enable viewing of dark cavities and optical fibers transmit the impage from the lens to the eyepiece. Using the fiberscope, we were able to get accurage egg counts and to see details of the nestlings that indicated age and development, including feather growth and whether the eyes were open. Nest checks were also quicker than using the standard light and mirror apparatus. Drawbacks include cost and, possibly, durability.
