Staying Put

Home is where the eagle stays! Today marks the 560th consecutive day that our wonderful Wallu has spent in a fixed home range at Lorna Glen in central Western Australia. Except for a few days where he was recorded about 60 km east of his territory for part of the afternoon, Wallu hasn't left home, roosting here every night for the past 18 months. This is a relatively small area for a large eagle, especially in such an arid environment, a sign that food supply in this habitat is ample. At the beginning of this study I expected the home range to be at least 100 km2, but Wallu occupies an area less than half this size. In the future tracking more adult eagles will give us a better idea of the average home range in this landscape.
