Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. Regardless of species, insects share presence a group morphologically conserved neuropils known collectively as central complex (CX). The CX is navigational center, involved sensory integration coordinated motor activity. Despite fact that our understanding behavior comes predominantly from ants bees, most what we know about underlying neural circuitry such work fruit flies. Here,...

Photoreceptor adaptation ensures appropriate visual responses during changing light conditions and contributes to colour constancy. We used behavioural tests compare UV-sensitivity of budgerigars after UV-rich UV-poor backgrounds. In the latter case, we found lower than expected, which could be result photon-shot noise corrupting cone signal robustness or nonlinear background adaptation. suggest that may necessary for allowing cones discriminate signals, such as bird plumage colours, against natural
