Red-cockaded Woodpecker (Picoides borealis).
The Red-cockaded Woodpecker is an eight-inch long woodpecker with a solid black cap and nape, and prominent white cheek patches, and the male has red on either side of the head rather than on the nape. Expand
ECOLOGICAL RELATIONSHIPS BETWEEN FUNGI AND WOODPECKER CAVITY SITES
Patterns evident among woodpecker nest sites that suggest microclimatic and microhabitat characteristics favoring fungal colonization of trees, wood pecker-favorable responses of trees to fungi, and ultimate use of the trees for woodPEcker cavity excavation are described. Expand
Downy Woodpecker (Picoides pubescens)
The Downy Woodpecker seldom accepts nest boxes, preferring to excavate a new hole yearly from 2 to 15 m (5 to 50 ft) high in a dead tree (Bent 1939). It takes from 13 to 20 days to excavate the… Expand
Hairy Woodpecker (Picoides villosus)
Pileated Woodpecker (Dryocopus pileatus)
Host factors limiting monogenean infections: a case study.
Results provide an explanation for the low burdens encountered in field studies: a majority of adult X. laevis in natural populations are likely to exhibit strong, relatively long-term, post-infection immunity after the loss of a previous infection. Expand

There were no consistent interspecific differences in the response of egg stages to low and high temperature shocks during early embryonic development in Protopolystoma xenopodis and P. orientalis isolates from southern Africa. Expand
The Role of Insectivorous Birds in Forest Ecosystems
A Quantitative Study of the Foraging Ecology of Downy Woodpeckers
- J. A. Jackson
- 1 March 1970
Both male and female Downy Woodpeckers use sub—surface foraging techniques to a greater extent during the winter and superficial techniques during the warmer months, and greater use of dead trees during winter is also indicated. Expand
Protopolystoma xenopodis (Monogenea) primary and secondary infections in Xenopus laevis
Primary infection with P. xenopodis can elicit strong, long-term protective immunity against re-infection in X. laevis, and reproductive output per initial infective stage for the primary exposure exceeded that for the secondary exposure by a ratio of 15:1. Expand
