Abstract

The effects artificial watering devices (guzzlers) have on chukar (Alectoris graeca) populations were studied in Juab County, Utah.

The effect of water was determined by a comparision of chukar populations near guzzlers with water to guzzlers without water. The closure of two guzzlers had a pronounced effect on the distribution of chukars and the number of chukars decreased significantly at the two guzzlers after their closure.

Water concentrated the chukars, therefore, influencing their activities. During the water-critical period, between 1 July and 1 October, frequent, possibly daily, trips were made to water by chukars.

Reproduction and chick survival was high in the vicinity of the guzzlers. In 1967, 21 chukar broods averaged 10.0 ± 4.6 young per brood while in 1968, 36 broods averaged 11.5 ± 5.2 young per brood.

In 1968, hunter success was exceptionally high averaging 1.3 birds per hour and 4.6 birds per hunter.
