Chris Lewey came back to MESA to catch up with the students. The focus of his presentation was how man shapes his environment, wildlife on the other hand is shaped by it. Chris' presentation on Mount Washington had the students "blown away".

Did you know that winter in Maine is technically a desert? That is why deciduous trees really lose their leaves. Once the tree get the signal there is less sunlight, they begin to set up shop for winter. Leaves are responsible for drawing up and releasing moisture through the process of transpiration. Deciduous means to totally drop off, kinda like our first teeth. Conifers on the other have needles that are designed to not lose their moisture. All leaves have the ability to capture sunlight and to use that to make carbohydrates. Chris reviewed the anthocyanins and xanthophylls.

From there, Chris spoke to bird migration. For example, the yellow rumped warbler weighs 10 to 12 grams, and needs all of that to migrate. Migration, the process of, ends up losing 70% of the birds that travel. Ospreys travel from Maine and go all the way to the coasts of Chile. Owls do not leave, as they feed on mammals that are here year round. 

He left off at a great place that is a natural lead into our Thursday trip to the beaver meadows at East Bear Paw. 

The MESA students bombarded Chris with so many questions. Big thanks to Chris for his patience and willingness to work with us. saw the rainbow today....right? These are the easiest sunrises you can catch. They are so late in the morning. 10 minutes up Jockey Cap. Easy.
