Evaluating habitat suitability using relative abundance and fledging success of Red-naped Sapsuckers
Article Abstract:
The effectiveness of the forest management requirement of leaving some snag (standing dead trees) and live trees in logged areas was tested in Red-naped Sapsuckers (Sphyrapicus nuchalis). The relative abundance and fledging success of the birds were compared in unlogged and in logged areas. The results showed that the relative abundance and fledging success between the two areas did not differ significantly, indicating that the strategy of snag and live tree retention in logged areas to provide suitable habitats for the Red-naped Sapsuckers is an effective one.

A quantitative analysis of woodpecker drumming
Article Abstract:
A study was conducted to examine the drumming patterns of a number of California woodpecker species to test whether the long-distance signal is species-specific. Posterior probability error rates were computed based on the accuracy of the posterior probability equation in relation to misclassification of species membership. Results suggested that signal equivocation between Northern Flickers and syntopic species was a selective pressure related to diagnostic long calls.

Do Woodpecker drums encode information for species recognition?
Article Abstract:
Research is presented concerning the responses made by four species of woodpecker to playbacks of Woodpecker drums. The differing responses made to sympatric heterospecific and conspecific drums are discussed.
