Hunger is not the Only Determinant of Nestling Begging Behavior and Parental Feeding in the Black-Billed Magpie Pica pica

Lee, S. I., Choi, J., & Choe, J. C. Nestlings can employ a combination of tactics to obtain provisioning from the parents. In this observational study, we examined whether nestling begging behavior reflects hunger level and how parents respond to nestling begging in the Black-billed Magpie Pica pica by putting small video-cameras in six

Molecular Tools for Species and Sex Identification in the Mixed-Species Flocks of Bean Geese and White-Fronted Geese

Kim, M. K., Lee, S. I., Lee, H., & Lee, S. Genetic studies on protected species can be difficult, particularly when they form a mixed-species flock with other species. The bean goose (Anser fabalis), which is internationally recognized as a threatened species, was observed to form overwintering foraging flocks with white-fronted goose (Anser albifrons)

Egg color polymorphism and morph-ratio variation in Korean populations of the Vinous-throated Parrotbill

Lee, J. W. & Jablonski, P. G. Understanding the occurrence of multiple distinct phenotypes in a population of a species, i.e., polymorphism, is one of the challenges encountered in evolutionary biology. Egg color polymorphism in birds is one example of morphological polymorphism and disruptive selection has been proposed as a hypothetical mechanism to explain

Biomimetic flow control based on morphological features of living creatures

Choi, H., Park, H., & Sagong, W. Despite the long history of biomimetics (or biomimetic engineering), a scientific discipline of implementing nature-inspired ideas to engineering systems for their performance enhancement, successful developments have been made only recently, especially in the field of flow control. In the present paper, we discuss flow controls based on

Camouflage through an Active Choice of a Resting Spot and Body Orientation in Moths

Kang, C. K., Moon, J. Y., Lee, S. I., & Jablonski, P. G. Cryptic colour patterns in prey are classical examples of adaptations to avoid predation, but we still know little about behaviours that reinforce the match between animal body and the background. For example, moths avoid predators by matching their colour patterns with

Wild Birds Recognize Individual Humans: experiments on magpies, Pica pica

Lee, W. Y., Choe, J. C., & Jablonski, P. G. The ability to distinguish among heterospecific individuals has been reported in only a few animal species. Humans can be viewed as a special type of heterospecifics because individuals differ widely in behavior, ranging from non-threatening to very threatening toward animals. In this study, we

Geographic variation in the acoustic signals of black-billed magpies (Pica pica) in South Korea and Japan

Lee, S. I., Lee, S., Nam, H. Y., & Choe, J. C. Black-billed magpies (Pica pica) are a highly sedentary species due to their short and round wings, which are not adequate for long distance flights. We investigated geographic variation in the vocal signals of magpies residing in South Korea and Japan (subspecies sericea).

Non-Parental infanticide in a dense population of the Black-billed Magpie (Pica pica)

Seo, K., Lee, W., Kim, W., Choe, J. C., & Jabłoński, P.G. We report the first case of non-parental infanticide in the Black-billed Magpie Pica pica. Using a video camera installed in the victims’ nest, we recorded repeated visits (over 4 days) of an adult (each time one bird) who attacked six nestlings at each

Effect of Sex and Bright Coloration on Survival and Predator-Induced Wing Damage in an Aposematic Lantern Fly with Startle Display

Kang, C. K., Lee, S. I., & Jablonski, P. G 1. Aposematic coloration in prey promotes its survival by conspicuously advertising unpalatability to predators. Although classical examples of aposematic signals involve constant presentation of a signal at a distance, some animals suddenly display warning colours only when they are attacked. 2. Characteristics of
