First Time

Observations of foraging birds showed that the summer diet of adult and juvenile spruce grouse (Dendaragapus canadensis) in southwestern Alberta included 31 taxa of fungi, vascular plants, and animals. The genus Vaccinium was confirmed as the major food source for these grouse during summer. For the first time, however, conifer needles and fungi were recorded as important components of the diet at this time of the year. The latter observations raised questions about the potential for bias, particularly in terms of the type of the food ingested and the time of day when it was consumed, in studies of the food habits of galliforms that are based only on analyses of crop contents.

Scientific Value

Lepidopterans play an integral role in high altitude Rocky Mountain ecosystems as larval herbivores and, more importantly, as pollinating adults. Lepidopterans also constitute a major food source for many other invertebrates and vertebrates in Rocky Mountain food chains. However, very little is known of the important lepidopteran aspect of ecology within Wyoming ecosystems, and virtually nothing of scientific value has been published on the lepidopterans of the National Parks in Wyoming.

AbstractXavier, J. C., Cherel, Y., Roberts, J., and Piatkowski, U. 2013. How do cephalopods become available to seabirds: can fish gut contents from tuna fishing vessels be a major food source of deep-dwelling cephalopods? – ICES Journal of Marine Science, 70:46–49. Cephalopods are important prey for numerous seabird species. However, the physical mechanisms by which cephalopods (particularly species considered as deep-dwelling) become available to seabirds are poorly understood, and it has recently been suggested that the discarded stomachs of gutted fish captured by tuna longliners can be a major source of deep-dwelling species. Here, we identify some deep-dwelling cephalopods that appear in the diet of seabirds, review the current knowledge of their vertical distribution, and compare the stomach contents of commercially captured tuna with those of seabirds foraging in the same area. The limited available information leads us to conclude that tuna longliners are unlikely to be a major source of deep-dwelling cephalopods for seabirds. However, much more information is required on the ecology of seabird prey, particularly commercially unexploited cephalopod species, which may be obtained from scientific cruises devoted to cephalopod biological research. In addition multispecies/foodweb modelling studies may be required to explore potential interactions between seabirds, their predators and prey, and commercial fishing operations.
