The Golden Penda (Xanthostemon chrysanthus), an exotic tree introduced from Australia, is commonly planted along roads in Singapore. It flowers profusely during certain months of the year, covering the crown with thick bunches of yellow blossoms that last a few days (above).
So far we have reported Brown-throated Sunbird (Anthreptes malacensis) as seen in this LINK and Blue-crowned Hanging Parrot (Loriculus galgulus), Rainbow Lorikeet (Trichoglossus haematodus), Yellow-vented Bulbul (Pycnonotus goiavier) and Javan Myna (Acridotheres javanicus) in this LINK visiting for its flower nectar.
The copious nectar is found at the cup-shaped depression at the base of the flower (above: view from above and LS).
Now we have documented another species that come to feed on its nectar – the Red-whiskered Bulbul (Pycnonotus jocosus pattani) (above).
