Extract

A small flock of 16 Blackface ewes occupying 40 acres of hill ground grazed as a fairly tight community. From observations over a complete year, 1960, it has been shown that sheltering behaviour was largely dependent on wind speed exceeding 24 m.p.h. Sheltering increased markedly at temperatures below freezing. Temperature above freezing, except for rapid falls in temperature exceeding 4° F., exerted little effect on sheltering. No relationship could be found between sheltering behaviour of the sheep and other factors which included rain, relative humidity, wind direction or season of the year.

It would appear therefore that the sensitivity of sheep to exposure is influenced more by wind speed than any other climatic factor.
