Canvasback – Feeding and Fighting Behavior

In April of 2008 I photographed some interesting Canvasback feeding and fighting behaviors at a local pond.   At the time I was still a relative novice at bird photography so I’ll say up front that this blog post is more about the behaviors than it is about image quality.  The almost white plumage and dark head made for a tricky exposure for a beginner and there was a significant issue with specular highlights caused by reflections off of the shiny mud.      Dive, eyes open On this day there was one drake feeding quite close to me and I was very interested in the whole process.  He would continually dive down to the muck at the bottom of the pond and come up with his head completely covered in thick dark mud.  Sometimes he would dive with his eyes open, like this.       Dive, eyes closed And other times he would dive with his eyes closed.  Either way, mud and grit in the eyes never seemed to be a problem for him.       Ol’ Muddy Head 1 When he would emerge, this is what he would look like.      Ol’ Muddy Head 2  And this.  It never failed – a true mud facial.  Canvasbacks are often referred to as the “aristocrats of ducks” but it’s hard to look very aristocratic with a face full of mud.      Shakin’ the mud off Occasionally he would try to shake as much of the mud off as possible but it never seemed to change the look of him…

Weather Loach in Utah – Another Invasive Species

  On December 12, 2007 I photographed this Common Goldeneye with a fish at Farmington Bay Wildlife Management Area.  At the time I didn’t pay much attention to what kind of fish it might be and then just kind of forgot about it.  Male Common Goldeneye with unidentified (at the time) fish    The moment of capture Then, on October 2, 2008, I took some photos of a Snowy Egret fishing, also at Farmington.  Finally, I became curious about the unusual fish – noticing the atypical elongated almost eel-like body in particular. I made some casual inquiries of refuge personnel about fish species present there but didn’t get anything definitive that would match this fish.   More time went by, then I finally showed Justina Parsons-Bernstein some of the photos and asked her about the fish.  She is the Director of The Great Salt Lake Nature Center at Farmington Bay WMA and she was also curious as to what species of fish it was so she sent some of my images to a vertebrate specialist with the state of Utah.  He keyed it out as a Weather Loach. It turns out that the Weather Loach or Dojo Loach as it is also known (Misgurnus anguillicaudatus) is quite a remarkable fish.  The name Weather Loach comes from the fact that it is highly sensitive to minor changes in barometric pressure and when it perceives such a change its behaviour becomes erratic, active and animated.  Humans have kept them captive as a weather indicator for centuries.  They are a very hardy species, capable of surviving poor conditions by swallowing atmospheric…
