Black-throated Sunbird – nectar sources

posted in: Feeding-plants | 0

“I have seen Black-throated Sunbirds (Aethopyga saturata wrayi) feed on a wide range of nectar sources, occasionally using nectar robbing techniques. I am sure the full list is protean and there are many where I am not able to ID the plant (especially wild flowers).

“Nectar sources seen on this occasion:
1. Abutilon pictum – commonly known as Redvein Abutilon, Red Vein Indian Mallow, Redvein Flowering Maple or Red vein Chinese lanterns (native to South America) (above).
2. Abutilon megapotamicum – called the Trailing Abutilon (native to South America). Nectar robbing technique used. See below (composite image of two shots merged to bring flower into focus).
