Thursday 28 April 2011 The Red Bat

The Red Bat (Lasiurus borealis), is aptly named due to its distinctive reddish coloring. and is one of the mammals in which the males and females are differently colored. The male's fur is brighter shades of red to orange-red; while the females are duller red, chestnut, or brick. Both sexes have a frosted appearance from their white tipped hairs; however females are usually more frosted. Medium-sized, the Red Bat averages 4 to 5 centimeters (1.5 - 2 inches), with its total length about 9 to 12 centimeters (3.5 to 4.5 inches), including the tail. It weighs between 7 to 19 grams (1/4 to 5/8 ounces).

The Red Bat is unique in that instead of roosting in caves, mining tunnels, or other interior spaces; it prefers to roost in the open in trees. Their range is from southern Canada, through the United States, and south to Chile and Argentina. They prefer forested areas, forest edges, or hedgerows. Their coloring helps them to blend in with the foliage, and hanging upside down, they look like dead leaves or pine cones. Although some Red Bats in the southern part of its range may stay in the same area year around, the northern ones migrate south in the winter, often in flocks, where they hibernate. A variety of locations are chosen for hibernation, often tree hollows, underneath shaggy bark, or even on the ground beneath fallen leaf litter.

The Red Bats are the first bats one usually sees flying around after sunset. Their favorite foods are moths and beetles, but they will settle for other insects, especially flying ones – the bigger the better. An unusual fact is that they follow the same routes each night for feeding. Predators include birter"> Even-toed ungulates
