bat : any of a widely distributed order (Chiroptera) of nocturnal usually frugivorous or insectivorous flying mammals that have wings formed from four elongated digits of the forelimb covered by a cutaneous membrane and that have adequate visual capabilities but often rely on echolocation — Webster
Bats are mammals of the order Chiroptera; with their forelimbs adapted as wings, they are the only mammals naturally capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti’s hog-nosed bat, which is 29–34 mm (1.14–1.34 in) in length, 15 cm (5.91 in) across the wings and 2–2.6 g (0.07–0.09 oz) in mass. The largest bats are the flying foxes and the giant golden-crowned flying fox, Acerodon jubatus, which can weigh 1.6 kg (4 lb) and have a wingspan of 1.7 m (5 ft 7 in).
The second largest order of mammals, bats comprise about 20% of all classified mammal species worldwide, with over 1,200 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiroptera, with megabats as members of the former along with several species of microbats. Many bats are insectivores, and most of the rest are frugivores (fruit-eaters). A few species feed on animals other than insects; for example, the vampire bats feed on blood. Most bats are nocturnal, and many roost in caves or other refuges. Bats are present throughout the world, with the exception of extremely cold regions. They are important in their ecosystems for pollinating flowers and dispersing seeds; many tropical plants depend entirely on bats for these services. — Wikipedia

- Biologists defy Cyprus' ethnic divide to protect...on April 15, 2021 at 3:03 pm
There's something regal in the sprightly step and curious gaze of the long-horn sheep that roam the hills near Varisia, an abandoned village inside a U.N. buffer zone that cuts across ethnically divided Cyprus.

Deep in a Jamaican cave is a treasure trove of bat poop, deposited in sequential layers by generations of bats over 4,300 years.

A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers.
- Plant a pollinator garden to supply food sources...on April 7, 2021 at 11:49 am
Pollinators serve a great purpose in helping pollinate plants and vegetables alike during many months of the year. Although wildflowers returned post-freeze, and many plants are beginning to show life again, most flowering was set back several weeks meaning food sources for pollinators are not available. Planting a few already-flowering plants or fast-growing seeds in your pollinator garden will help them get through while other plants recover.
- A diversity of wildlife is good for our healthon April 5, 2021 at 7:00 pm
A growing body of evidence suggests that biodiversity loss increases our exposure to both new and established zoonotic pathogens. Restoring and protecting nature is essential to preventing future pandemics. So reports a new Proceedings of the National Academy of Sciences (PNAS) paper that synthesizes current understanding about how biodiversity affects human health and provides recommendations for future research to guide management.
