Spotted sandpiper and chick


While vacationing near Hope, BC (Sunshine Valley), I noticed a sandpiper on a small gravel island in a nearby stream.  I returned later with my camera hoping it would still be there.  I was thrilled to find that it was, with a pair of chicks as well.  

While photographing the adult, I noticed it repeated a peculiar up-and-down bobbing motion of its hind end.  This is called teetering; you can see a video of it doing this here.  This repeated tail-bobbing has resulted in some uncommon nicknames for the species including teeter-peep, teeter-bob, jerk-or-perk bird, teeter-snipe, and tail-tip.  

What was even more interesting was that the chicks were engaged in exactly the same behaviour.  I almost laughed out loud when I noticed this as I followed them with my viewfinder.  Apparently, they do this nearly as soon as they hatch.

There is no understanding as to why these birds teeter, but according to one site I read, they may increase their bobbing rate when anxious or stop it altogether when courting.  Whatever the reason, I admit to being enchanted by it.

Thanks for reading.

Do herons and egrets belong in the same or different groups?

Top:  White-faced heron, Little blue heron, Green heron Bottom:  Reddish egret, Black-crowned night heron, Yellow-crowned night heron, Great blue heron The three species of heron I have seen in Canada are the green heron, black-crowned night heron, and great blue heron.  The white-faced heron I photographed in New Zealand, and the other three were taken in southern Texas near the Gulf of (Ahem) Mexico.  And, if you didn't notice, there is an egret in the group. The body shape of herons and egrets appears to be the same, which isn't a coincidence.  Egrets are really just a type of heron.  They both belong to the Ardeidea.  The term egret typically applies to white heron-like birds or heron-like birds with a glossy coat.  Below are photos of some egrets. Snowy egret, Great egret, Cattle egret The only North-American member of the Ardeidea that I haven't seen or photographed is the tri-coloured heron.  Cattle egrets are an old-world species foun...

Harjit Bahia - Science teacher and colleague from Garibaldi died August 2, 2024

You will be missed Mr. Bahia.  You made a difference and we are sad you are gone. I keep in loose contact with my fellow retired teachers from Garibaldi Secondary School.  I talked with my long-time friend, Mike Lynch, today, and discovered that Hargit died over the summer.  Unbeknownst to him, he had an underlying heart condition and passed away after working out on his treadmill.  The date was August 2, 2024. I was shocked to hear this.  He was only 49 years old, turning 50 some 3 months later.  It was a shock to everyone, for he was loved by all who knew him.  As a teacher, Mr. Bahia was kind and fun.  He contributed to students in many ways and was always available to help those in need.   For myself, I knew him as a fellow science teacher and taught in the adjoining room to him.  He was always available to help, share ideas, and work together.  Easy to approach, I found that I could talk to him about anything and appreciat...

My longsuffering search for the Western Meadowlark

Image
Am I going to disturb a species I am photographing enough to negatively affect its relationship with the ecosystem?  This is an important ethical question that needs to be asked when looking to photograph a particular species.  And it's one that I don't think we do nearly often enough. I recognize the desire to capture remarkable images; I have been in search of premium photos the bulk of my adult life.  There is the personal connection - just the joy associated with doing something well and the praise we seek when others recognize it.  There is the professional connection - doing something as part of a job, assignment, or class.  Then there is the financial connection - the hope to win a contest, publish an image, or sell prints.   These are all worthy goals in their own right, but none of them should be the reason behind disturbing a species, especially ones that are endangered or are at a critical period in their life cycle.  Essentially it boi...
