Becky, the common one is Black Flying-fox. Grey-headed Flying-fox is here too. Both have a joint roost down at the golf course with nesting Royal Spoonbills, Cattle Egrets and White Ibis. I must go and photograph again. The Royals are gorgeous with their breeding plumes.
The smaller ones I must get identified. I think there are at least 9 species of microbats here.
Melanie, are there butterflies in Iceland? Make sure you start going through your bird plates early so they get easily imprinted in your memory for sure and quick identifications. Do you have a chance at Musk Ox, Polar Bear and Narwhale? What a wonderful trip to do.
