Some bat species like the spotted bat survive by migrating in search of food to warmer areas when it gets chilly. The Northern long-eared bat spends winter hibernating in caves and mines.
Bats have few natural predators — disease is one of the biggest threats. The disease — named for a white fungus on the muzzle and wings of bats — affects hibernating bats and has been detected in 37 states and seven Canadian provinces. This deadly syndrome has decimated certain species more than others. Scientists are working to understand the disease. You can help by avoiding places where bats are hibernating.

Babies sometimes develop a flattened head when they're a few months old, usually as a result of them spending a lot of time lying on their back. In most cases they aren't a major cause for concern, as they don't have any effect on the brain and the head shape will often improve by itself over time.
Your baby won't experience any pain or other symptoms, or any problems with their general development. A young baby's skull is still relatively soft and can change shape if there's constant pressure on a particular part of their head.
Occasionally, a flattened head can be caused by the plates of the skull joining together too early. This is known as craniosynostosis. Speak to your health visitor or GP if you're concerned about the shape of your baby's head or think they may have problems turning their head. A slightly flattened head isn't usually anything to worry about, but it's a good idea to get advice early on so you can take steps to stop it getting any worse. Medically reviewed by Karen Gill, M.
