Descriptions of Sciurus ingrami Thomas, 1901 nests are not available in the literature. In this study, a survey was made of the distribution of S. ingrami nests in a woodlot located near to the headquarters of the Serra do Caraça Reserve, in state of Minas Gerais, where there is a high concentration of Syagrus romanzoffiana (Chamisso) Glassman palm tree, among other exotic tree species. The nest-building behaviour and the nest characteristics, such as height from the ground, total circumference, diameter of the entrance, and the position of the nest in the tree - in the crown, along the trunk or in a side branch, were described.

Building Behaviour

AbstractEIBL-EIBESFELDT (1961) and THORPE (1963) have suggested that nest-building in various species is reinforced by stimuli associated with the acquisition of a finished nest. HINDE & STEVENSON (1969, 1970) have proposed, by contrast, that individual nest building activities may persist and act as reinforcers regardless of whether or not they lead to nest formation. Evidence for these views is discussed. Five experiments designed to test HINDE and STEVENSON'S view arc described. In Experiments I and 2, naive female mice were given access to hoppers of paper strips for 14 days. Carrying of strips into the nest box declined rapidly to zero as the nests reached completion, but gathering of strips from the hoppers continued at the original level. It is concluded that carrying and subsequent events associated with nest acquisition are not necessary for the initiation and maintenance of gathering. In Experiments 3 and 4, access to paper strips was made contingent upon performance of an arbitrary operant (key pressing). The majority of subjects continued to key press and gather paper after the cessation of carrying, but at a reduced level. Furthermore, key pressing to gather only occurred if the operant-reinforcer distance was very small. It is concluded that gathering per se is less reinforcing than gathering plus carrying and building. In Experiment 5, amount of gathering per reinforcement was varied by using different widths of paper. Number of reinforcements per session was positively related to paper width, providing further evidence that gathering is reinforcing. It is concluded that gathering is at least to some extent autonomously controlled, and that it is a weak positive reinforcer. However the results also suggest that other reinforcing events are present at a later stage in the nest building sequence. Some theories concerning the causation of selfsustaining activities, and their implications for unitary drive theories, are discussed.

SUMMARY A 20h light:4h darkness lighting schedule induced a high level of gathering behaviour in intact canary hens in autumn and winter. The same schedule was relatively ineffective in ovariectomized birds, indicating that the ovary is normally a mediator in the photostimulation of nest-building behaviour. However, exogenous oestrogen given to ovariectomized birds on normal winter daylengths resulted in only a slight increase in gathering behaviour, while in similar birds previously exposed for 5 weeks to a 20h light: 4h darkness schedule a rapid increase in gathering occurred to a level approaching that of intact birds on long photoperiods. A similar difference in response to hormone injection with and without exposure to long photoperiods was also seen with testosterone and with oestrogen and testosterone in combination. Nest-building was not completely eliminated in ovariectomized birds. Ovariectomized birds on 20h light:4h darkness per day gathered more than those on normal daylengths. This is unlikely to be a consequence of the longer time available for building activity as it can be suppressed in the long-photoperiod birds by methallibure, a gonadotrophin inhibitor. The possibility that a non-ovarian mechanism is involved in building behaviour is discussed. The results suggest that although the effect of long photoperiods on nest-building is mediated largely by oestrogen there is a second factor operating without which oestrogen is relatively ineffective. Possible mechanisms for this effect are discussed.

Incubation Pattern

Abstract(1) Parental behaviour, and its development from incubation behaviour during the reproductive season, is described. (2) Day to day observations of the natural situation showed that elements of the incubation pattern persist throughout the post-hatching period but progressively decline in quantity, duration and completeness. (3) Substitution of eggs for chicks also showed that the readiness to show incubation responses in a standard incubation situation declines progressively during the post-hatching period. (4) A certain amount of experience with hatched chicks renders Black-headed Gulls incapable of immediately returning to sustained incubation behaviour if the conditions of the incubation period are restored. (5) Failure of the eggs to hatch results in extension of the incubation behaviour period beyond the normal time. (6) Premature introduction of hatched chicks in the nests of incubating gulls can cause the gulls to switch to parental behaviour and so end the incubation behaviour period before the normal time. (7) The timing of the change from incubation to parental behaviour is thus mainly a matter of external control. (8) Certain of the relationships found to hold between responses having an incubation function and responses having a nest-building function in the earlier phases also hold in the post-hatching period.
