Mountain Monday

This winter the most numerous bird species hanging around our area is the Mountain Chickadee. They appear to make up the core of mixed flocks roaming the neighborhood and slightly outnumber the Red-Breasted Nuthatches and Black-Capped Chickadees. These guys have a wonderful feisty-spunky-gritty- character that makes them a real treat to have around on a winters day. As spring arrives they will move back up into the hills but for now we are thoroughly enjoying having the around.

Winter Friends

We have been lucky to have two and sometimes even three Brown Creepers hanging around the area this winter. They have been the first to arrive to the trees in the morning steadily working their way up and down the bark of the spruce and pines on their daily quest for sustenance. Tiny birds weighing on average seven grams and at most  fine inches in length they are well camouflaged yet their presence looms large and is a welcome sight in the quiet of the winter forest.

Hello Neighbor

A recent report published in Science Daily describes the results of a recent research study published in the journal Current Biology supporting the hypothesis that when under attack from insect herbivores plants indeed communicate with each other.1

No, they don’t scream, but use chemicals called Volatile Organic Compounds and release them into the atmosphere and are detected by their neighbors.

One of the major findings from the study is that when plants are under attack the compounds released become more similar between species suggesting a type of cross species communication.

The Author of the study Andre Kessler describes the results of the study as follows:

“What we very often see when plants get attacked by pathogens or herbivores is, they change their metabolism,” Kessler said. “But it’s not a random change — in fact, those chemical and metabolic changes are also helping them cope with those attackers. It’s very much like our immune system: though plants don’t have antibodies like we have, they can fight back with pretty nasty chemistry.” 2

Interesting stuff.

The article in Science Daily is an easy read and a little splash of color to beat back a dull January day might be just what the doctor ordered.
