The common blossom bat (Syconycteris australis) also known as the southern blossom bat or Queensland blossom bat, is a megabat in the family Pteropodidae. The common blossom bat feeds mostly on nectar and pollen rather than fruit. [1] It is one of eight Pteropodidae species on mainland Australia. It is one of the smallest of all nectarivorous megabats.

Description

They are small, weighing only 17.5–21 g (0.62–0.74 oz). [2] Body length excluding legs is around 60 mm (2.4 in) long. [3]

Distribution and habitat

They are found in the Maluku Islands, Salawati, Biak, Yapen, New Guinea, the Aru Islands, the Bismarck Archipelago, Manus Island, the D'Entrecasteaux Islands, the Louisiade Archipelago, New South Wales, Australia, and eastern Queensland, Australia. They range from 0–3,000 m (0–9,843 ft) above sea level. [1] They are found in upland tropical rainforests and the Littoral Rainforests of New South Wales. [4]

Behaviour

They roost singly or in small groups, which makes estimating population based on visual observation difficult. [1] They generally roost in the rainforest subcanopy. They may change roosts daily however (when food was available) distances between subsequent roosts in NSW were short (average 42m at Iluka or 125m at Harrington). [5] They are probably important pollinators, as they carry six times as much pollen as birds while also traveling further in a night. The bumpy satinash tree is an important food source for this species in North Queensland, as 95% of all pollen observed on their fur comes from this species on bats caught near flowering trees. Their home ranges are 12–1,796 ha (0.046–6.934 sq mi). When foraging, they prefer to fly along riparian zones. [6]

Because their energy demands are high and the energy content of a single flower is low, they must visit the equivalent of 36-48 coast banksia flowers every night. [2] To meet their energy requirements, they are active for a large proportion of the night. [5] During the full moon, they will delay their departure from their roosts. This suggests that they are afraid of predators such as owls that hunt by sight. [7] Other potential predators include goannas and arboreal snakes. [5] Domestic cats are known to capture and injure them. [8] They will enter torpor when food availability is low, or when the ambient temperature is below 26 °C (79 °F). Contrary to other bat species, torpor is more common and pronounced in the summer than in the winter. [9]

Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera Acerodon and Pteropus—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described.

<span class="mw-page-title-main">Bat</span> Order of flying mammals

Bats are flying mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most 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 millimetres in length, 150 mm (6 in) across the wings and 2–2.6 g in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox reaching a weight of 1.6 kg and having a wingspan of 1.7 m.
