The Ethiopian hedgehog (Paraechinus aethiopicus) is a little-known desert-adapted hedgehog species indigenous to the Middle East. We have been conducting the first-ever research in the Gulf Cooperation Council (GCC) countries on behaviour and ecology of free-ranging Ethiopian hedgehogs in Qatar using radio-tracking. We found that the average range size of Ethiopian hedgehogs much larger than those of other hedgehogs studied in temperate zone environments. In spite of the mild winter in Qatar hedgehogs appear to become inactive during winter. The results also suggest an interesting and puzzling relationship between length of inactive (hibernating) period and weight loss. Hibernating animals are predominantly females. One of the mainstream hypotheses to explain the benefits of hibernation is helping animals to save energy during the cold period when energy expenditure substantially exceeds energy intake. However, in our study population hibernating hedgehogs lose more body weight than do non-hibernating animals during the cold months. This may be related to the possible increase of food availability during cold months in Qatar around irrigated farms and domestic rubbish dumps, which have become increasingly available in the last few decades in Qatar.
