The Phyllostomidae, also known as New World leaf-nosed bats, are among the most ecologically diverse mammal families. [6] This variation is measured by diversity in skull morphology and diet-related characteristics: Phyllostomidae consists of species that have evolved physical modifications for insectivory, frugivory, hematophagy, nectarivory, and omnivory.
The bat flies fairly rapidly on occasion, but the usual foraging flight is slow and buoyant, and more nearly silent that of most bats. [1] In level flight Macrotus wings make a soft fluttering sound that is less sharp and carrying than the sounds made by the wing beats of most other bats. The method of landing is most interesting.

They range in size from the Malayan tailless leaf-nosed bat, at 3 cm (1 in) and no tail, to the striped leaf-nosed bat, at 13 cm (5 in) plus a 4 cm (2 in) tail. Like all bats, hipposiderids are capable of true and sustained flight , and have wing lengths ranging from multiple species with 3 cm (1 in), to the giant roundleaf bat at 13 cm (5 in).
A heterodyne bat detector does not give a very accurate measurement of the frequency of a bat call, One reason is that the call frequencies can easily vary by 1 kHz or more due to the doppler shift. To track these changes and to get a more precise frequency, a frequency division bat detector or a time expansion bat detector is used using a ...
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is ...
