Communication of Young Black-Tailed Gulls, Larus crassirostris, in response to Parents Behavior
Chung, Hoon,Cheong, Seok-Wan,Park, Shi-Ryong The Korean Society for Integrative Biology 2004 Korean journal of biological sciences Vol.8 No.4
In the breeding colony of black-tailed gull, as nests of conspecific neighbors are very closely located, chicks are permanently exposed by sound and visual stimuli produced by adult conspecifics approaching their nests. The chicks, therefore, may need to learn ways to appropriately respond to their parents approach. In this study we experimentally manipulated sensory stimulation that is potentially provided by the parents to the offspring. Chicks incubated in the laboratory were exposed to a mew call of the conspecific adult. Then they were tested in three situations differing in sensory stimulation: 1) visual stimulation only, 2) auditory stimulation only, and 3) Simultaneous visual and auditory stimulations. We observed occurrence of different response of the chicks, which were categorized into three behaviors (begging call response, chirirah call and pecking behavior). We also investigated intensity of the chicks call in response to the different stimulations and the degree of response with age. The chicks exposed to only auditory stimulation made significantly more chirirah calls. The intensities (dB) of the mew call and chicks chirirah call were directly correlated. On the other hand, when chicks just saw the stuffed adult gull, they responded significantly more with a begging call and pecking behavior. In the situation of costimulation, the chicks responded with a begging call and pecking, but less frequently than visual stimulation only. The results suggest that young black-tailed gulls use call repertories to properly respond to parents behavior. Such results suggest an evolutionary process for uncreasing their survival rate in a group breeding site.

Individual Recognition between Siblings of the Young Black-tailed Gull (Larus crassirostris)
Chung, Hoon,Lee, Hyun-Jung,Park, Shi-Ryong The Ecological Society of Korea 2002 Journal of Ecology and Environment Vol.25 No.6
We had 18 eggs artificially hatched in a mass breeding place of black-tailed gulls and examined the individual recognition between young siblings in a laboratory environment. The results of the experiment showed that the young gulls selectively responded to their siblings and non-siblings at an early stage after hatching. It was shown that they began to recognize the begging call among the voice signals of siblings and non-siblings 15-16 days after hatching, and the chirirah call 11-12 days after hatching. Also, more significant results were shown with the chirirah call than with the begging call. In an experiment of visual recognition between siblings and non-siblings, the young black-tailed gulls approached their siblings significantly 9-10 days after hatching. The recognition between young siblings in a mass breeding place provides an important evolutionary indicator in terms of their social behaviors.

Begging Signals for Food in Young Black-Tailed Gulls, Larus crassirostris
Hoon Chung,Ha-Cheol Sung,Seokwan Cheong,Shi-Ryong Park 한국실험동물학회 2005 Laboratory Animal Research Vol.21 No.4
We divided young black-tailed gulls in laboratory into two groups, high condition group (fed hard mass) and low condition group (fed soft mass). In order to see special behaviors of begging, we tested two condition groups at levels three levels of food deprivation (1, 4, 12h). We found out that both begging call rate and pecking rate increased in direct proportion to fasting time of food deprivation. Begging call rate, call intensity (㏈), and pecking rate were significantly greater in the low condition group. The food quality was also core factor changing the rate in begging call, pecking and call intensity (㏈). Such begging behaviors were shown more in the late stage than the early stage after hatching. It seems the means of encouraging parents' responses, considering increased feeds in direct proportion to the high metabolic rates of young gulls. These issues require further experimental study under natural and laboratory conditions with parents in this species.

Effect of begging call playbacks on growth of great tit, Parus major, nestlings
김규정,임신재,손승훈,황현수 한국산림과학회 2014 Forest Science And Technology Vol.10 No.1
This study was conducted to clarify the effects of begging call playbacks on the growth of great tit, Parus major, nestlingsin artificial nest boxes. The mean body mass of nestlings significantly differed between the control (60 dB playbackintensity), playback 1 (80 dB), and playback 2 (100 dB) groups. However, mean tarsus length was not different based ontreatment. The daily body mass and tarsus length gain of nestlings in playback 2 were higher than in the control andplayback 1 groups in this study. Further long-term research is needed to understand the relationship between beggingbehavior of nestlings and parental care in the great tit.

This study was conducted from April 2012 to June 2012 to analyze breeding status of Black woodpeckers (Dryocopus martius) in the Gayasan National Park. Nest height, tree diameter which a nest built and altitude at the nest site of Black woodpeckers were 17.4 m, 63.8 cm and 587 m, respectively. A pair of Black woodpeckers completed a clutch in 4 eggs on 7 May and 3 of eggs hatched on 24 May 2012. Both female and male incubated eggs and never left eggs without one of parents. A male more contributed to build a nest than a female. Incubation duration was higher in a male than in a female. Nestlings made a begging call in a nest during the growing period. Begging frequency of nestlings increased from 11 days up to 20 days after hatching. After then, nestlings reduced begging and fledged a nest 24 days after hatching. This study provided information of breeding ecology to protect and manage population of Black woodpeckers which are endangered species in South Korea.
