If possible, it is always good to spend a bit of time checking out the eye-ring of the Yellow-eared Spiderhunter Arachnothera crysogenys.  The similar looking Spectacled Spiderhunter has a full and broader eye-ring whereas the Yellow-eared has a thinner and incomplete eye-ring.  In the field these spiderhunters defend their favourite fruit and flower bunches aggressively.
