Crimson Sunbird – tongue

posted in: Morphology-Develop. | 0

I had an opportunity to image the tongue of the Crimson Sunbird (Aethopyga siparaja siparaja) as it called out near me (above). The tongue of sunbirds, like other nectar feeders, is tubular and fringed at the tip (brush-tipped). They collect nectar by capillarity. I am uncertain if the Crimson Sunbird tongue is bi-tubular at the tip as in some Sunbirds.
