HERONS

Herons are quite a varied family of long legged, long necked birds. Ardeidae, as they are termed include 72 recognised species worldwide which includes egrets and bitterns. Within West Dunbartonshire you are most likely to come across the Grey Heron, simply known as the "heron" standing patiently at the waters edge. 


GREY HERON Ardea cinerea

Where to see them : Almost any open water such as rivers, canals and park ponds. 

They are mainly grey above and greyish-white below. They have a long neck with a strong, straight, dagger-shaped yellow bill that they use to harpoon fish and long legs for wading . They have an unmistakeable black eye stripe that extends into the black feathers at the back of their head.

They can often be see along our rivers and canals, usually standing quite still. They tend to be solitary, but may congregate in groups up to a dozen to avoid inclement weather. The slower metabolism of herons compared to some of their waterside neightbours such as moorhens and ducks is rather slow. They don't need the same volume of food, but when they do catch something it is quite nutritious. This same slowness means that a heron can quite happily stand for hours at the waters edge until prey comes within reach. its sharp beak then acts like a javelin and spears the prey be that a fish or frog. Its own shadow on the water can act as false security for small fish. 

While quite shy of people, you may still see one quite close up if you approach quietly and not directly towards it. Most of us though only see them belatedly when we disturb them almost hidden by reeds.

All done, for now. Two mallard drakes sail past in admiration.

Elegance in the morning sunshine.

The heron and its shadow prowl in perfect tandem for small fish in the shallows. With patience and very slow movement, even standing quite still for ages, this can confuse the fish into false security in the shadow. A flash of the harpoon results in a tasty meal.

And while there is some privacy, some thorough preening.

If you compare this heron to those in the picture above you will notice some differences. It does not have the black "shoulder" patches and has a streaky grey chest as compared to the almost white of the others. This means that it is fully grown, but still immature. The regular adult was seen a few hundred metres further downstream on the same day and is most probably its parent.

As it matures the shoulder patches become more pronounced.

Herons symbolize tranquility, serenity, elegance, and grace. They are most often found wading through shallow waters and calmly stalking their aquatic prey. They can be found in art through the ages including tapestries. The following is a photograph taken in the River Leven and then given a digital effect that is reminiscent of a tapestry.
