Arthropods smaller than 1 mm, ants, isopods, and arthropods with aposematic colorations were excluded from the counts because these are rarely consumed by insectivorous birds. |
Additionally, taxonomically troubling taxa such as Crataegus makes identification and quantification of aposematic species extremely difficult. |
Clusters amplify the signal of aposematic coloration, and individuals may participate in group regurgitation or displays. |
To further investigate the effects of prey contrast on predator behavior, I conducted an experiment with young chicks as predators on live aposematic and nonaposematic prey. |
Some types of caterpillars are indeed poisonous or distasteful and their bright coloring is aposematic. |
Alternatively, they may be used to signal to predators, the classic example being aposematic coloration in species that have noxious defenses, such as skunks. |
