Colonial Breeding

The hypothesis that social stimulation, derived from the presence and activities of conspecifics, can hasten and synchronize breeding in colonies of birds was tested. A modified playback/recorder system was used to continuously exaggerate the amount of colony sound available to zebra finches throughout their courtship period. Males that heard ‘sound supplements’ generated from their own colony sang more than males in control colonies that did not receive playback; males that heard samples from a different colony, sang at an intermediate level. Females that were exposed to the vocalizations of their mate and playback from a colony other than their own, laid eggs earlier and more synchronously than females in control colonies. Females that heard the vocalizations of their mate along with playback samples generated from their own colony, laid eggs more synchronously but not earlier than control females. Both acoustic treatments caused females to lay larger clutches. Social stimulation influences the breeding schedule and clutch size in zebra finch colonies. If there are advantages associated with these effects, social stimulation may contribute to the maintenance of colonial breeding systems.

AbstractSocial interaction with a song tutor is often found to be important for the song learning process in songbirds, but the mechanism is still unclear. The main aim of this study is to find indications for contingencies between singing and interactive behaviours, between and within tutors and tutees, which might influence the song learning process of zebra finches (Taeniopygia guttata). To this end we observed the interactions of eleven juvenile zebra finch males with their fathers (the tutors) and their mothers during the sensitive phase for song learning, and examined four different types of possible contingencies. The evidence for these contingencies was not very strong: (1) We found some weak indications that a tutee can anticipate tutor song by preceding tutor behaviour. There were no indications that (2) tutor song is contingent upon subsequent behaviour of the tutor, that (3) juvenile males can control singing of their tutor by preceding operant social behaviour, or that (4) social behaviour of the tutor reinforces singing of the tutee. We found some indications that the juvenile males attend actively to the tutor song. Furthermore, we found that the juvenile males maintained more mutual interactions with their father than with their mother. In general, we did not find any clear relationship between aspects of social interaction and song copying in zebra finches.

Sensitive Phase

AbstractYoung male zebra finches (Taeniopygia guttata) normally copy their song from one tutor when given a choice of two. Interaction is known to be a key feature of the learning process and this study examines the way in which one particular type of social behaviour, aggression, may affect tutor choice. Female raised zebra finches were given a choice of two song tutors, which had been pre-selected for differing levels of aggression, during the sensitive phase for song learning. A young bird was significantly more likely to learn from the tutor that was more aggressive to him, as found earlier by Clayton (1987). In addition, behavioural observations suggest that aggression towards the young bird was the cause rather than an effect of tutor choice. There was no significant relationship between the relative level of tutor aggression and the amount of his song copied. Changes in the level of aggression over the tutoring period are also discussed.

Zebra Finch Song

AbstractThis paper examined the relative importance of visual and vocal cues for song tutor choice. In the first study zebra finches, Taeniopygia guttata, and Bengalese finches, Lonchura striata, were housed with two song tutors at independence, a zebra finch singing Bengalese finch song and a Bengalese finch singing zebra finch song. All the males tended to learn from the conspecific song tutor, irrespective of whether they had been raised by a pair of conspecifics, the female alone or cross-fostered to a pair of the other species. In the second study zebra finches were housed at independence with two conspecific song tutors, one with a normal song and one which sang Bengalese finch song elements. There was no tendency to learn zebra finch elements which suggests that species-specific elements are not important for song tutor choice in zebra finches. Other vocal differences between the tutors such as length of the song phrase and species-specific call notes might bias learning in favour of the conspecific. Visual differences between the two species, both in appearance and behaviour, seem to be important. Parental cues before independence appear to be relatively uninfluential. However, siblings may be important, both the species and number per clutch: this is a factor which has been overlooked in previous studies of song learning.

Choice Tests

AbstractMale zebra finches, Taeniopygia guttata castanotis, were normally-raised by zebra finches or were cross-fostered to Bengalese finch, Lonchura striata, foster-parents until 40 days of age. Following isolation until day 100, half the birds in each group were housed with a zebra finch female for seven days, isolated for three days and then housed with a Bengalese finch female for seven days. The other birds were exposed to females in the reverse order. Subsequent double-choice tests showed that all the normally-raised birds preferred zebra finch females whereas the preferences of cross-fostered males depended on the order of exposure to the two females: those exposed first to a Bengalese finch female preferred Bengalese finch females whereas of those exposed first to a zebra finch female, some preferred zebra finches, some preferred Bengalese finches and some showed no marked preference for either female. In order to examine the question of why the latter group showed such marked individual variation in their sexual preferences, a further group of males were cross-fostered to Bengalese finches and exposed to a zebra finch female and then to a Bengalese finch female and their behaviours were observed from day 21 until day 40 and for the two, seven-day periods with the females. The results show that, when comparing brothers within clutches, the one that begs and is fed more by by its foster-parents develops a stronger preference for Bengalese finch females and that the more song phrases a male directs to the zebra finch female during the first seven-day period, the stronger the sexual preference for zebra finch females in the double-choice tests. Hence, our results confirm and extend those of IMMELMANN et al. (1991) and KRUIJT & MEEUWISSEN (1991) that sexual imprinting may be a two step process. As a first step, information about the parents is learnt during a sensitive period early in life. In a second step, this information has to be tested for its validity for the selection of a sexual partner during first courtship encounters. It is this second step where the previously stored information is stabilized in memory. Giving conflicting information during the first and the second step, one can show that interactions between the young male and its parents as well as with its first sexual partner influence the final preference it shows in subsequent double choice tests.

Zebra Finch Song

Vocal acquisition in songbirds and humans shows many similarities, one of which is that both involve a combination of experience and perceptual predispositions. Among languages some speech sounds are shared, while others are not. This could reflect a predisposition in young infants for learning some speech sounds over others, which combines with exposure-based learning. Similarly, in songbirds, some sounds are common across populations, while others are more specific to populations or individuals. We examine whether this is also due to perceptual preferences for certain within-species element types in naive juvenile male birds, and how such preferences interact with exposure to guide subsequent song learning. We show that young zebra finches lacking previous song exposure perceptually prefer songs with more common zebra finch song element types over songs with less common elements. Next, we demonstrate that after subsequent tutoring, birds prefer tutor songs regardless of whether these contain more common or less common elements. In adulthood, birds tutored with more common elements showed a higher song similarity to their tutor song, indicating that the early bias influenced song learning. Our findings help to understand the maintenance of similarities and the presence of differences among birds' songs, their dialects and human languages.

Intraspecific variation in egg size, clutch size, and timing of laying was studied in captive-breeding zebra finches (Taeniopygia guttata) maintained under conditions of constant temperature, humidity, photoperiod (14 h light: 10 h dark), and ad libitum food supply. Individual variation was marked in the experimental population: egg size 0.915–1.342 g, clutch size 2–7 eggs, and laying interval 4–13 days; however, within individual females egg size (r = 0.742) and clutch size (r = 0.588) were highly repeatable between first and second clutches. Body condition explained only 8% of egg size variation, and clutch size and laying interval were independent of body condition. Clutch size was negatively related to laying interval: females laying later relative to pairing laid smaller clutches (b = −0.175 eggs/day). Body mass of breeding females decreased by 1.57 g (9% of initial mass) during laying of first clutches; mass loss was positively related to initial body condition (R2 = 27.8%) and total clutch mass (R2 = 7.6%). Mass loss was lower (0.47 g) during laying of second or replacement clutches than during laying of first clutches. Individual variation in reproductive effort in captive-breeding zebra finches is very similar to that in free-living avian populations. Laboratory studies on captive-breeding species can provide a valuable approach for the study of proximate physiological mechanisms underlying intraspecific variation in reproduction.

This paper is a descriptive study of the spatial preferences of the zebra finch, Taeniopygia guttata, when exposed to a novel environment. 18 subjects were observed in a cubic open field of 1 × 1 × 1 m during four 30-min. sessions. Two spatial variables were considered, height and center/periphery. Data show that birds did not position themselves randomly in the open field but chose more frequently the central and higher part of the enclosure and that general activity was greater when the animal was in the center rather than on the periphery. There were no sex differences in the height preferred, but females spent significantly more time in the center than did males. The type of activity engaged in by the birds was also important in relation to the place occupied.

Specific Learning

AbstractMale zebra finches, Taeniopygia guttata, which have been cross-fostered to Bengalesc finches, Lonchura striata, learn Bengalese finch song elements with as much accuracy as a male learning from his natural father. However, these elements are sung in phrases which are more nearly zebra finch length and lack the repetitiveness typical of the elements in a Bengalese finch phrase. Male Bengalese finches are also capable of learning song from a zebra finch foster-father. Males vary substantially but they tend to produce fewer, more widely spaced zebra finch elements in a Bengalese finch-length phrase. Both species show selective song learning and it is suggested that phrase length and the absence or presence of repeated elements might act as important cues for species-specific learning. Cross-fostered Bengalese finches seem to learn less than cross-fostered zebra finches: possible reasons for this are discussed.
