Surprising dunlin find - Pete Hughes, Ecologist - June 2017
During last winter I was lucky enough to find a spot alongside Chichester Harbour where 3 or 4 short-eared owls roosted. These are winter visitors to the Harbour and inhabit open landscapes such as marshes, rough grassland and heaths. Not surprisingly, where the birds had been resting there were a number of owl pellets - the regurgitated bundles of bones, fur and feathers that the owls cannot digest. I was interested to know what they had been eating, so I collected them up and took them home to have a closer look.
I was expecting the owls to have been feeding mostly on small mammals - voles, mice and shrews, but when I started dissecting the pellets, I found mainly the remains of birds, particularly waders. Incredibly, one of the leg bones in one of the pellets had a ring on it - a German ring, from the Hiddensee ringing scheme.
As usual, when I find a ringed bird, I put the details of the ring into www.euring.org a website provided by the European Union for Bird Ringing, the organisation that holds data for all European bird rings, although this time I didn't even know what species of bird it was...
I waited and finally received an email from Germany telling me the details of the bird:
It was a dunlin, which is a small wader that winters in Chichester Harbour in large numbers - around 10-12,000 of them each year. So far, so normal, however this bird was ringed on 30 August 1999. The precise location was Insel Langenwerder, a small island on the North coast of Germany in the Baltic sea. The bird was in its first year at ringing, making it a little over 17 and a half years old when it died!
The British Trust for Ornithology lists dunlin as having an expected lifespan of 5 years, with the oldest ringed bird recorded being 19 years and 3 months. So it's fair to say that this dunlin was fairly elderly when it was caught by a short-eared owl in late February 2017. Perhaps Chichester Harbour holds the secret to long life?
15 May 2017 - Mating Oystercatchers Caught on Camera
We see a lot of things here at Chichester Harbour. But our most recent glimpse into the lives of our resident wildlife is definitely one of our most entertaining. Earlier this month two Oystercatchers were caught on camera during a rather intimate moment at Ella Nore Spit near West Wittering. The sight of birds mating in the Harbour in the springtime is to be expected but not it's often photographed. These pictures were caught by a motion-activated trail camera set up to capture images of rare Little Terns coming to nest.
We went back to the camera today to check for images and low and behold, they were at it again! All this activity is proving successful as we also found a nest with three eggs close by.
You can easily spot Oystercatchers around the harbour and coastline; just look out for their black- and-white plumage, large stocky build and long orange bill, and listen for their distinctive call. However, you might not catch them in such an exposing position during an afternoon stroll. The area where the Oystercatchers were pictured had a protective electric fence surrounding it to guard against foxes; perhaps the reason why the birds found it such a perfect place to copulate!
We set up cameras like this around Chichester Harbour to monitor rare or endangered animals, but footage like this is always a bonus and made us smile. If you spot any rare animals or unusual sightings, don't forget to share them with us on Facebook or Twitter.
