摘要:

AbstractCentral nervous action determines the cyclic sequence of mating behavior in theTeleogryllus commodus♂ and the patterns can appear predictably without external stimulation. However, the copulatory act triggers the onset of the cycle and peripheral factors, such as the presence of a ♀, may modify performance and duration of some of the patterns. The highly flexible capability of the central nervous system is thereby acknowled

摘要:

AbstractGoshawks and pygmy owls responded to recordings of passerine alarm calls by correctly orienting to their source. Theseeet, or “aerial predator” alarm call which is generally assumed to be “non‐localizable”, while it elicited fewer responses than did mobbing calls, was nevertheless accurately localized by all birds that did respond. The evolution of alarm calls is discussed in terms of efficient prey communication, following Darwin's “antithesis principle”, rather than predator selection for non

摘要:

AbstractThe range of elevated positions in which captiveCercopithecus aethiopsmonkeys held their tails is apparently a continuum of display behavior. Different positions correlated with different behavior: Any might be adopted during a great diversity of activities, but with the more anterad positions a monkey might forego non‐agonistic behavior to attack, and with the more posterad to withdraw. When the tail was held straight upright locomotion for any end was momentarily improbabl

摘要:

AbstractTheof a desert species ofCalomyrmexpossess large mandibular glands which contain a brightly coloured secretion.This study investigates the role of the gland as part of the alarm/defence system of the species. The alarm promoting properties of the secretion are demonstrated. The defensive role of the secretion is studied from three aspects; the possible toxicity towards other insects; the repellent and/or repugnant properties towards another ant species; the responses of insectivorous vertebrates toCalomyrmexand to other food items, some of which are treated by application of the secretion prior to presentation. The significance of the colour of the secretion is also discussed.

摘要:

AbstractWe recorded the song of six male canaries during their first and second year of life to see if we could detect systematic age‐related changes. Soundspectrographic analysis revealed that many syllables from the previous year were omitted and many new ones were added. There was a significant increase in syllable repertoire during the second year. The proportion of single‐element syllables increased between year 1 and year 2. These results indicate that neural pathways responsible for song learning in canaries remain plastic in adulthood. We suggest that the larger song repertoires of older ♂♂ confer a reproductive advantage by acting as a more potent stimulu

摘要:

AbstractUnder semi‐natural conditions, behavioural schedules differ in juvenile and adult Bar‐headed geese and in pairs with and without goslings. Goslings also interfere in the pair's synchronisation of behavioural actions. Three families and two pairs (10 adults and 18 juveniles) were observed. The observations were performed once or twice a month on 2–5 successive days. On these days a family's activities were recorded once every 20 min between sunrise and sunset. The results are discussed with respect to findings in wild‐living Bar‐headed geese and other goos
