“…Our results corroborate findings from previous research on blue tit nestlings ( Cyanistes caeruleus ) in which nestlings from the lower temperature treatment tended to be smaller than those from the higher temperature treatment, although not significantly so (Nord & Nilsson, ). We predicted that Low‐treatment nestlings would be smaller than High‐treatment nestlings, and High‐treatment nestlings would not differ in size (mass, wing and tarsus length) from naturally incubated nestlings given that ~38°C is presumed to be optimal based on experimental work with a congener of the robin (Kuehler & Good, ). When comparing raw means across treatments, we did not find significant differences in mass, wing, or tarsus length, but when we restricted comparisons to focal chicks and their foster nest‐mates (i.e.…”

“…Eggs were placed in cotton-lined 50-ml Corning™ Falcon™ tubes for transport to the laboratory. Collected eggs were randomly placed into one of two temperature categories: 36.1°C (presumed suboptimal incubation temperature; Lundy, 1969; designated as "Low") and 37.8°C (presumed optimal incubation temperature; Kuehler & Good, 1990; designated as "High") both set to 60%-65% relative humidity (Kuehler & Good, 1990). Early on in the experiment, our Low incubation temperature was 35°C, but during the initial round of egg collections, it became evident that 35°C was too low for robin eggs (0% hatching success, n = 11).…”

For oviparous species such as birds, conditions experienced while in the egg can have long‐lasting effects on the individual. The impact of subtle changes in incubation temperature on nestling development, however, remains poorly understood, especially for open‐cup nesting species with altricial young. To investigate how incubation temperature affects nestling development and survival in such species, we artificially incubated American robin (Turdus migratorius) eggs at 36.1°C (“Low” treatment) and 37.8°C (“High” treatment). Chicks were fostered to same‐age nests upon hatching, and we measured mass, tarsus, and wing length of experimental nestlings and one randomly selected, naturally incubated (“Natural”), foster nest‐mate on days 7 and 10 posthatch. We found significant effects of incubation temperature on incubation duration, growth, and survival, in which experimentally incubated nestlings had shorter incubation periods (10.22, 11.50, and 11.95 days for High, Low, and Natural eggs, respectively), and nestlings from the Low treatment were smaller and had reduced survival compared to High and Natural nestlings. These results highlight the importance of incubation conditions during embryonic development for incubation duration, somatic development, and survival. Moreover, these findings indicate that differences in incubation temperature within the natural range of variation can have important carryover effects on growth and survival in species with altricial young.

Zoos focus on welfare, conservation, education, and research related to animals they keep. Academic institutions emphasize description, experimentation, modeling, and teaching of general and specific animal biology and behavior through work in both laboratory and field. The considerable overlap in concerns and methods has increased interest in collaborative projects, but there is ample room for closer and more extensive interactions. The purpose of this article is to increase awareness of potential research collaborations in three areas: (1) control and analysis of behavior, (2) conservation and propagation of species, and (3) education of students and the general public. In each area, we outline (a) research in zoos, (b) research in academics, and (c) potential collaborative efforts. Zoo Biol 27:470-487, 2008. (c) 2008 Wiley-Liss, Inc.
