Rainton Meadows Nature Reserve

With Spring 2011 almost upon us I have been preparing for another season of nature photography on my own doorstep. In my home town of Houghton le Spring you'll find Rainton Meadows Nature Reserve, which is more than handy for me as it's only a few minutes drive to the site.

Rainton Meadows and Joe's Pond can be found by following the brown signs from the A690 between Durham and Sunderland. By bus, the services 222 and 220 regularly leave Park Lane in Sunderland, or the bus station in Durham and set down at the nearby Mill Inn. There's a short walk under the A690 continuing until you reach the last roundabout of the industrial estate. The entrance to the Reserve is called Mallard Way.

During the Spring and Summer months I make regular visits, usually with my son who gets as much enjoyment from the place as I do. Many species of wildlife can be seen here, including Foxes, Hares, Rabbits and Owls, as well as breeding birds such as Swans, Geese, Grebes, Kestrels and Warblers, to name just a few.

Armed with a 300mm lens and Canon 7D body I usually pull in some decent shots, especially during April to July when the Mute Swans are nesting and the cygnets readily feed from visitors - subject to parental approval of course. Don't get too close as you might get a clout! There is normally two new families of Mute Swans on the reserve each year and each nest is normally visible from the designated paths.

Swans usually pair for life and have elaborate courtship rituals including the famous heart shape they make with their necks. They normally start breeding in their fourth year. The male, or cob, is larger than the female or pen and when together the longer neck, larger webbed feet and larger black berry of the male make identification much easier. Unfortunately many young swans die each year but some live to about 25 years in favourable conditions. The cob will establish a territory large enough to supply his future family with sufficient food and will valiantly defend it against all comers, whether they be other swans, foxes or intrusive humans. Swans are protected birds and it is illegal to harm them or steal their eggs.

The male and female choose the nest site together and use any material within about 40 feet to make the nest. The pen lays between 1 to 12 eggs, the average being 6. The eggs are laid every other day and only when the last egg has been laid does incubation start. The incubation period lasts about 35 days and the pen only comes off the nest for very short periods to drink and stretch her legs. The cob takes over after a recognition head lifting ceremony. The cob will defend the nest against foxes, dogs and other predators. Cygnets normally take to the water 24 hours after the last cygnet has hatched, usually in May. The parents do not feed them, but the pen will 'foot paddle' to bring food to the surface for cygnets to eat and pull out reeds which the young would otherwise be unable to reach. One parent will always be on guard and they often travel in line with one parent at the back, the other in front. The pen will carry the young ones on her back.

The swan family is very close and if a cygnet is lost, the parents will often look for it up to a week. Natural predators are pike, foxes, mink and cold wet weather. Unfortunately man poses further hazards. Nature has been clever with the swan's moulting period when they cannot fly. The moult takes about 6 weeks and for non-breeding birds takes place about July time. A pair with cygnets moult at different times, first the pen and then the cob in August to September so that one of them can always defend the young.

Here is a couple of photographs I took on Sunday morning (27th Feb) - the first was taken at Rainton Meadows (Pond 1) and the second at Joe's Pond which is situated at the other end of the reserve, near the Rainton Bridge Industrial Estate . Lastly, I have uploaded a short video clip of a nest site in the reeds at Pond 1, captured last May, showing newly hatched cygnets. Only a few chicks are visible but the full clutch of ten eggs hatched successfully.

A nice taster for what is round the corner in 2011. Spring is almost here!
Cheers, catch ya later.
