Congradulations to Konstantin Bock who completed his BSc thesis this week on active photolocation in birds. His work suggests the possibility that the evolution of facial markings in insectivorous birds has been influenced by their foraging strategies. Indeed, he found that substrate gleaners are much more likely to have bright facial plumage compared to sally strikers. It is yet unclear whether this pattern is caused by sally-strikers having darker features to reduce glare, or substrate gleaners redirecting ambient light to increase the visibility of hiding prey items, or both. Very promising results that warrant further investigation. Well done!
