A large variety of predatory species rely on their visual abilities to locate their prey. However, the search for prey may be hampered by prey camouflage. The most prominent example of concealing coloration is background-matching prey coloration characterized by a strong visual resemblance of prey to the background. Even though this principle of camouflage was recognized to efficiently work in predator avoidance a long time ago, the underlying mechanisms are not very well known. In this study, we assessed whether blue tits ( Cyanistes caeruleus ) use chromatic cues in the search for prey. We used two prey types that were achromatically identical but differed in chromatic properties in the UV/blue range and presented them on two achromatically identical backgrounds. The backgrounds had either the same chromatic properties as the prey items (matching combination) or differed in their chromatic properties (mismatching combination). Our results show that birds use chromatic cues in the search for mismatching prey, whereupon chromatic contrast leads to a ‘pop-out’ of the prey item from the background. When prey was presented on a matching background, search times were significantly higher. Interestingly, search for more chromatic prey on the matching background was easier than search for less chromatic prey on the matching background. Our results indicate that birds use both achromatic and chromatic cues when searching for prey, and that the combination of both cues might be helpful in the search task.

Environmental variation was quantified at nestboxes monitored as part of a prospectively long-term project on the ecology and evolution of great tits Parus major and blue tits Cyanistes caeruleus in Warsaw, Poland. Nine axes of environmental variation were investigated across 9 different urban sites, for a total of 565 specific locations (here: nestboxes). Data was collected on the ground, with the use of GIS and remote sensing using the following methodology:...

Some passerines incorporate aromatic plants in their nest cups, and several hypotheses have been formulated to explain this behaviour. One of those, the Drug Hypothesis, states that aromatic plants present in nests have positive effects on nestlings’ development through increased immune function. In this study, we aimed to examine if experimental addition of aromatic plants had positive effects on reproductive performance (the number of fledglings produced and nestling survival rate) and nestling development (weight and tarsus length). In addition, we study whether those potential effects were more noticeable in different brood sizes–small and large–through an observational approach. We expect that large broods, due to increased resource competition between nestlings, will benefit more from aromatic plant incorporation, as compared to small broods. Nestlings were significantly heavier in 2015 as compared to 2016 and 2017 and in small broods. No effect of treatment was observed in nestling weight. Although there was no overall effect of treatment on nestling tarsus length, nestlings from aromatic nests had significantly longer tarsi as compared to nestlings from control nests, in large broods.
