Significant Diurnal Variation

The diet of nestling mountain chickadees (Parus gambeli) (55 694 items in 34 730 feeding trips) is summarized. Larval Hymenoptera, Lepidoptera, and adult Coleoptera were the most common prey in the nestlings' diet. A single prey item was usually delivered per trip. Significant intersexual differences in delivery of specific prey types were rare; intersexual differences in overall diets declined with nestling age. Prey delivered by individual parents exhibited decreasing day to day variation as nestlings aged. Frequency of prey preparation declined with nestling age, with feeding frequency, and especially with increasing number of prey delivered per trip. Delivery of some prey, such as spiders, changed as a function of nestling age, whereas delivery of other prey was more directly related to calendar date and, by implication, to prey availability and environmental conditions. Take of most prey exhibited significant diurnal variation related to prey behaviour and to periodicities in nestling hunger state. Time spent waiting at the nest entrance often took up a greater portion of each foraging trip, and was more variable, than prey preparation time or travelling time between nest and foraging site and should be incorporated into foraging models.

AbstractWe allowed seven willow tits, Parus montanus, to store and retrieve with retention intervals of 1, 7, 21 and 56 days, in four experimental rooms. Retrieval success decreased over time, indicating a decaying memory for cache locations. Compared to what could be expected by chance, retrieval success was better after all retention intervals. Our results suggest that - after the longer retention intervals - this might depend on preferences for certain types of caching locations rather than memory. If both general and individual preferences are controlled for, birds retrieved significantly better than expected one and seven days after storing, but not later than that.

AbstractWe measured body temperature of Mountain Chickadees (Poecile gambeli) and Juniper Titmice (Baeolophus ridgwayi) at different times of day and under a range of ambient temperatures in order to determine the use of nocturnal hypothermia in seasonally acclimatized small passerines. Our findings show both species used nocturnal hypothermia year-round. Depth of hypothermia was inversely correlated to body mass in Juniper Titmice but not in Mountain Chickadees. In both species, depth of hypothermia did not vary seasonally but nocturnal body temperature was regulated 3–11°C lower than daytime values. Nocturnal energy savings range from 7%–50% in chickadees and from 10%–28% in titmice. These nocturnal energy savings translate into ecologically important reductions in daily energy expenditures for these two species.Hipotermia Nocturna en Individuos de Poecile gambeli y Baeolophus ridgwayi Aclimatados EstacionalmenteResumen. Medimos la temperatura corporal de Poecile gambeli y Baeolophus ridgwayi a diferentes horas del día y en un rango de temperaturas ambientales para determinar el uso de hipotermia nocturna en pequeñas aves paserinas aclimatadas estacionalmente. Nuestros resultados muestran que ambas especies presentaron hipotermia nocturna durante todo el año. La profundidad de la hipotermia estuvo inversamente correlacionada con la masa corporal en B. ridgwayi, pero no en P. gambeli. En ambas especies, la profundidad de la hipotermia no varió estacionalmente, pero la temperatura corporal nocturna estuvo regulada 3–11°C por debajo de los valores diurnos. El ahorro nocturno de energía varió entre 7%–50% en P. gambeli y entre 10%–28% en B. ridgwayi. Estos ahorros nocturnos de energía se tradujeron en reducciones ecológicamente importantes en los gastos diarios de energía para ambas especies.
