Harlequin Duck Program Report #3: 1999 CWS Surveys

In response to a general lack of knowledge on the abundance and distribution of the Harlequin Duck within Alberta, the Canadian Wildlife Service in cooperation with Alberta Environment undertook helicopter surveys of the eastern slopes of Alberta in 1998 and 1999.

In 1999 the survey area encompassed streams along the eastern slopes of Alberta between the North Burnt Timber River in the Red Deer River watershed and the Narraway River in the Smoky River watershed. Ground truthing was provided by foot surveys on the McLeod River conducted by Bighorn Wildlife Technologies Ltd.

This document contains summaries of the 1999 Harlequin Duck helicopter surveys conducted in the eastern slopes of Alberta between the North Burnt Timber River (southern boundary) and north of the Willmore Wilderness Area (northern boundary).
