Little Jonesy

May 8, 2022 | Diary, Family, Wildlife

Little Jonesy at 27 days old, looking around after being weighed and measured. He is in good condition and though he cannot fly yet, he will soon start to stretch his wings and be more adventurous.  At present, he is still relying on his mum for his milk feeds. Today he weighs 4g and his F.A. measurement is 27.96 mm.

In the photo and video below Little Jonesy is echolocating and showing off his pearly whites: his tiny new little teeth. Unfortunately, many people mistakenly see this as aggression; however, by emitting echolocating calls bats can understand their surroundings.  Echolocation is used for navigation, foraging and hunting in various environments. Bats can detect their insect food whether it is mid-flight, perched on a small branch or hiding under a leaf.  Echolocation calls can be emitted orally or nasally depending on bat species/family.  Bats emit different sounds and then listen to them as they bounce back. This way they can gauge the distance and direction of their insect prey. Bats are not aggressive, although like any wild animal, if frightened they may bite to defend themselves.
