#Invasive Mink Threatens South america's Largest Woodpecker Invasive American minks may threaten the largest woodpecker species in South america according to new research.
The Magellanic woodpecker a relative of the extinct ivory-billed woodpecker lives throughout the Andes of Chile and Argentina.
The Peskiest Alien Mammals Though the team did not make direct observations of a mink attacking a woodpecker they collected several pieces of evidence to argue their case which they detailed earlier this month in the journal Biological Invasions.
For instance the team found an adult Magellanic woodpecker which they had outfitted with a radio-tag for an unrelated study dead within a mink den.
On a separate occasion the team observed a mink creep up on a woodpecker looking ready to pounce at about 1 foot away (30 centimeters) until a student scared it off to prevent the attack.
and woodpeckers feeding in the same areas of the forest floor on separate occasions but sometimes within minutes of each other suggesting the animals share the same habitat.
This would make the woodpeckers vulnerable to predation if the minks had this intent. The team thinks the woodpeckers have adapted to feed on the forest floor rather than holing up more cautiously in trees
because they historically have had no natural predators on the island. Â They may have become naã ve by not having been exposed to terrestrial carnivores Jimenez told Livescience.
It's very easy for a carnivore to pounce on a woodpecker and kill it.
if the woodpecker populations decline Jimenez told Livescience. The team next plans to attach GPS units to the woodpeckers to better assess their distribution across the island
and understand the ecological consequences of their potential decline in an effort to develop management plans in response to the invasive mink population.

if native bark-foraging birds including woodpeckers and nuthatches were feeding on the emerald ash borer.
They hoped that unlike other exotic invasive species which run amok in new regions because of the lack of predators to keep them in check the emerald ash borer might meet its match in native predators--bark foraging birds like the woodpecker and nuthatch.
the woodpeckers alter their behavior in a way that allows them to find emerald ash borers more efficiently
and woodpecker activity in the area said Christopher Whelan an avian ecologist with the Illinois Natural history Survey UIC adjunct assistant professor of biology
and painted all the holes they found in the bark of each tree--a different color each for large round woodpecker holes for the characteristic crescent-shaped holes mature emerald ash borers
and after the bark was stripped the students could identify woodpecker holes that penetrated into emerald ash borer galleries
This was looking at woodpecker foraging at a fine tree-by-tree scale said Flower.
Their results proved that woodpeckers were indeed choosing to prey on emerald ash borers--eating 85 percent of the emerald ash borer in an infested tree.
the numbers of the predator in this case woodpeckers and other bark foraging birds increase either because they were moving into the area
--which showed that the numbers of three woodpecker species and the white-breasted nuthatch the important bark foraging birds in this region increased as the emerald ash borer increased.
and the functional response we found we have really powerful evidence of the potential of the woodpeckers
Woodpeckers won't save a tree once it's infested but they may save the forest.
The research suggests that the woodpeckers are likely slowing the spread of emerald ash borer.
Woodpeckers may not be able to snuff them out but they may be able to control them said Whelan.
#Increase in woodpecker populations linked to feasting on emerald ash borerthe scourge of forests the emerald ash borer
The four species of birds considered in the study Effects of the emerald ash borer invasion on four species of birds included three woodpeckers that are known to forage on EAB-infested ash trees
--the downy woodpecker hairy woodpecker red-bellied woodpecker--as well as the white-breasted nuthatch a common bark-gleaning species that is also a potential predator of EAB.
We can take heart that native woodpecker species are clearly figuring out that EAB is edible
Between the time EAB was detected first in 2002 and 2011 relative numbers of red-bellied woodpeckers
Populations of downy and hairy woodpeckers initially declined significantly and then fluctuated however the downy woodpecker was at a significantly higher level relative to control sites during the 2009 bird survey season
and hairy woodpecker populations were significantly higher during the 2011 season. Both for forests and urban trees the emerald ash borer has been devastating said Michael T. Rains Director of the U s. Forest Service's Northern Research Station and Director of the Forest Products Laboratory.
The Forest Service is helping cities and states prepare for and recover from EAB invasion with research on the insect ash trees'resistance to EAB and biological control.
whose beaks are more than 12 millimeters wide such as toucans and large cotingas. In undisturbed patches of forest on the other hand large-gaped birds still make their homes
More flexible in the Mediterraneanin the Atlantic as well as Mediterranean domain the observations were consistent with the data available on the ecology of the species. M. bechsteinii prefer roosts carved out by woodpeckers in the trunks of living oak trees located inside the forest
The study found that species sensitive to human impacts include the black-throated blue warbler black-throated green warbler hairy woodpecker hermit thrush ovenbird scarlet tanager and the winter wren.
and stress from the emerald ash borer is woodpecker damage because the beetle larva is a food source for the woodpecker.
Unfortunately once these symptoms appear the beetle has already been in the tree for a few years
of Ornithology's Team Sapsucker is taking on another big challenge. In early May the team will head to the American Southwest following a new birding route they call El Gigante.
and California says Sapsucker captain Chris Wood. It's a brand-new route for us with new challenges and lots of unknowns.
The Sapsuckers'route will take them through areas where habitat for birds and other animals is under heavy pressure from changes in land use and severe ongoing drought.
