I Swan! A Great Egret!

 

Sometimes my eyes play tricks on me.  The other day I thought I saw a mute swan on the pond.  I was not pleased.  I most certainly do not want swans on “my” pond.  While lovely to look at, and evocative of ballet and fairy stories, they are a menace. Mute swans are an “introduced” species, that is to say brought here by artifical means.  Highly aggressive, they  quickly clear a body of water of any other fowl.  The balance of an ecosystem can be affected in very little time.  While the population explodes, they eat up vegetation on the bottom of the pond, sometimes driving valuable plants to extinction. 

Looking again, I saw long legs.  That “swan” had a pair of gams that Anne Miller would be proud of!  It was a Great Egret.  During the spring and summer egrets of several kinds are not uncommon on our shoreline.  But in Farmington, fifty miles or more from Long Island Sound, an egret is something of an event.  This one may be  a migrating bird perhaps using the nearby Farmington River to head south. 

good egretI have never before seen an egret at Hill-Stead. We  sometimes get sandpipers feeding on our little mudflat, but it’s not a steady thing.  That’s about it for shorebirds.  In migration we get some nice ducks.  But egrets, no.

Egrets and swans have good  stories.  The egret is the symbol of the National Audubon Society.  At the end of the nineteenth and the early twentieth century, egrets were hunted nearly to extinction due to the fashion of using their plumes in the hat trade.  As Audubon Societies sprung up  and with the passage of the Migratory Bird Treaty Act of 1918, egrets rebounded.  Today they are not of any specific conservation concern.  Using an impressive beak  they are a graceful predator of small fish, frogs and other aquatic fauna.   Egrets are sometimes hard to spot.  Standing motionless for long periods they wait for the right moment and in the right light cannot be seen until they strike. 

Swans are native to Northern Europe and Central Asia.  A big bird, in historic days it was considered by royalty to be tasty eating.   Indeed, the custom of “swan upping” in England is an annual census of the swans on the Thames River.  The tradition comes from the monarchy’s protection of  its game birds.  To foil poachers, all swans were marked as the property of the Crown, so cygnets (baby swans) were marked as such each spring.  Today the census is used more for educational than gustatory purposes. 

Around the time the Great Egret was being saved from extinction, swans were being imported to America for their stylish looks.  Essentially an accessory or fashion statement, the bird’s regal bearing was  just right for the huge estates of Long Island and the Hudson Valley.  Today, a pair of swans runs about $500.  I heard somewhere that a flock of swans currently numbered at about 14,000 started with five imported birds on some Long Island Estate.  Caveat emptor.

See you on the trails,

    I never knew this about swans. I’ve only ever seen two swans while I’ve been hiking. There are plenty of great egrets around here though. They are beautiful birds too.

    Geese are kind of mean, too. I’ve been chased by a goose one too many times.

    The non-native swans are Mute Swans (Cygnus olor.) There are two species of native swans in North America. There is the Tundra Swan (Cygnus columbianus) and the Trumpter Swan (Cygnus buccinator). Trumpeter swans are extremely rare especially in the East but Tundra swans from the Arctic spend the winter along the Atlantic coast of the US. If you do spot swans (this time of year especially) look carefully to see if they are native Tundra swans.

      Quite right! I should have made this clearer in the post-the “undesireable” ones are the Mute Swans. Sadly, it is rare to see the Tundra Swan around here, though I am told they pop up from time to time on Connecticut’s shoreline. Thanks for making an important point Kirk! Cheers, Diane
