Between a Rock and Hard Place

This blog isn't about birds.  Well, not entirely.  Recently the Peabody Museum (Link here) ran a geology hike though New Haven's East Rock Park (Link here) lead by Copeland McClintock, one of their Geologists.  The idea of understanding more of the geology and natural history appeals to me.  While I didn't expect to become an expert after just one walk, I thought that any information would benefit my understanding of the natural world.

Thoughts of a simple passive walk were quickly disspelled by the fact that when I first arrived, articles, clipboards, maps, and colored pencils were shoved into hands.  We were also put to work learning the three different kinds of rocks (sedimentary, igneous, and metamorphic) and then we were quizzed with samples.  McClintock then took us on a whirlwind history tour of the planet and then East Rock.  We were introduced into the Cooling Columns of Basalt and the New Haven Formation of Arkose.  The Triassic New Haven Arkose and the Jurassic Basalt helped us understand how rocks interact and showcase our planet's history.

We also learned to look at and use the tools of a geologist.  Learning how to look at rocks, measure angles of rock intrusions, and how to identify the evidence of glacial activity.  While I am not going to even pretend to think that I could do this on my own, I did enjoy learning how to see the world how a geologist see it.  As a birder, I most often use that lens to see the natural world.  Geologists look at East Rock and see the movement of rock, intrusions of igneous rock, and the evidence of glacial activity.  I enjoyed the Peabody's walk and can't wait to get out and see more of the natural world!

Told you there would be some birds on this one

A First for Connecticut

For a few weeks, Connecticut Birding experienced a first, a Black-Chinned Hummingbird.  While I had seen my first one of these beautiful birds in Texas in May, it was great to see one in CT and see this record BCHU.  This wonderful find turned up at a private residence and the owner was kind enough to let a number of birders see this record little fella.

Record birds represent an interesting facet of ornithology and bird migration.  How did the bird get here?  How is it surviving in a strange environment?  What is compelling it to stay?  Are we even sure this is a rare bird?  Not that I have any answers to these questions.  I think its worth reflecting on the voyage that this migrant has made before it leaves and hopefully returns to its flock.

That last one was inspired by what I always say when I see a rare bird.  Am I sure that's a rare bird?  For this BCHU, I am fairly certain that it is a rare bird.  Since it was a CT First I decided to fill out a Rare Bird Report Form.  Even if this form wasn't the best one, I really enjoyed the experience of filling out the form.  As a closing, I leave you with a selection from said form. Until the next time...

"Since CT is home to the Ruby-Throated that was the first bird that I compared the bird I found to.  The first thing that I noticed was the unusual chin markings and eye markings. The Chin markings are the ones that lead to me to verify that this is a BCHU.  They are clearly different from a RTHU and the photos match the descriptions found in Sibley’s Bird Guide. "
