We rarely get blossom bats into care, but they have all come in from entanglement on barbed wire. Many die from exposure on the fence, because they are so small (1o-20gms) and burn up energy very fast.
We use a diet originally developed at the Territory Wildlife Park near Darwin, but has been modified along the way by different people.
The original diet is:
500mls apple juice
150g raw sugar
150g glucose powder
120g soy-based human breast milk replacer (s26soy or infasoy)
Freeze in small blocks and bring out as required to come to room temperature. Feed about 15mls a night in shallow containers e.g. lids from fruit juice bottles.
They especially like banana flowers and Myrtacae family blossom.
Other additions to this diet are Lorikeet mix, substitute mango/apple juice for apple juice, Wombaroo high protein powder and Ensure powder. We are currently using:
500 mls apple & mango juice
75 g raw sugar
75g glucose powder
60g Wombaroo high protein
60g Ensure powder (We always have it because we use it with the Tube-nosed bats. Expensive to buy so can leave out)
90g Wombaroo Lorikeet mix
There are 2 species of Blossom bat in this area, the Northern blossom bat (Macroglossus minimus) and Eastern/Common blossom bat (Syconycteris australis). The Syconycteris consumes some fruit especially figs and syzygium, but otherwise their diet is pollen and nectar. Although very similar in appearance, Syconycteris is slightly larger (17 – 23 gms) and ‘psycho’ with handling compared to the much calmer Northern species (10-20gms). The Northern has narrow skin flaps along the inside of the legs and a very small stub of a tail.
