Bee deaths

[Catb]

I have a palm tree with a large spay of flowers sprouting out. The bees were there yesterday. Now they are back but all dying on the ground under the tree. The flying foxes come at night for the flowers and noisy minor birds during the day. Could their urine on the flowers be killing the bees? I'm in the Gold Coast region, Australia.

Got any more information than that?

Visually inspect, after the rain, some water could pool, mould and algae is more likely to occur in sections this year. SEQ I've noticed flies, midgies, mosquito are present. As well more lichen, fungi, mould, algae is present.Who said climate change isn't real...
What type of palm tree is the suspect tree? Does it smell different?
