I tested this prediction by comparing foraging hop rates by 19 Painted Redstarts (Myioborus pictus) - insectivorous birds in Arizona, USA. Redstarts often use flashy displays of open wings and tail to flush their prey and to subsequently chase the prey in air. Such flush-displays make the prey conspicuous and easy to detect. Hence, foraging mode affects relative availability of conspicuous versus cryptic prey: birds foraging with frequent flush-displays encounter conspicuous prey more often then birds foraging with infrequent flush-displays. As predicted, the hop rates during foraging with infrequent flush-displays were lower than hop rates during foraging with frequent displays.}, type={Text}, title={The painted redstart (Myioborus pictus L.) search rate of a cryptic versus conspicuous prey: a field test of optimal search models}, URL={http://www.rcin.org.pl/Content/117560/PDF/WA058_91641_P2840-T51_Eko-Pol-A-Nr-3.pdf}, volume={51}, number={3}, journal={Polish Journal of Ecology}, publisher={Polish Academy of Sciences.
