![]() ![]() It is usually a Downy Woodpecker that you see at feeders as they are more common. the effects of predation by woodpeckers on western pine beetles into a direct. Reminiscent of a troupe of wide-eyed clowns, Acorn Woodpeckers live in large groups in western oak woodlands. These findings highlight how potential effects of smoke on animal behavior may be widespread and exacerbate negative impacts of increasingly common "megafires", even in fire-adapted ecosystems.Ĭopyright © 2023 Elsevier Inc. Length: 5.5-6.7 in (14-17 cm) Weight: 0.7-1.0 oz (21-28 g) Wingspan: 9.8-11.8 in (25-30 cm) Although visually very similar to the Hairy Woodpecker, it is a third smaller and with a smaller beak compared to other woodpeckers. the acorn woodpecker and the lewis woodpecker. ![]() A group member is always on alert to guard the hoard from thieves, while others race through the trees giving parrotlike waka-waka calls. Acorn Woodpecker eats the egg of a Western Wood-Pewee (Contopus sordidulus). Their social lives are endlessly fascinating: they store thousands of acorns each year by jamming them into specially made holes in trees. We show that between 20, ∼14% of the acorn woodpecker population in the US experienced fire, potentially exposing on average 89.42% of the range to atmospheric smoke annually. Reminiscent of a troupe of wide-eyed clowns, Acorn Woodpeckers live in large groups in western oak woodlands. Associations between birds decreased, and individuals were less assorted by group in co-visitation networks, suggesting less inter-individual coordination on smoky days. ![]() On smoky days, birds spent more time at their home territory and reduced visitation to others, especially to distant territories. Using automated radiotelemetry, we illustrate how smoky conditions are associated with changes in behavior of acorn woodpeckers (Melanerpes formicivorus), a flagship species of oak (Quercus spp.) savannas of western North America. The Acorn Woodpecker is an oak woodland specialist, relying on oaks for food, shelter and nest cavities. Wildfire smoke exposes wildlife to hazards and mortality from particulate matter on a scale larger than the area impacted by fire 3, 4.
