Project 366 – Post No. 155 – Juvenile Ring-billed Gull

What is Project 366? Read more here!

It had been raining all night and all day and it did not look like the rain was about to stop any time soon. So I wrapped up my camera in it’s rain gear, donned a rain jacket and rubber boots and headed to Hawrelak park. There were not many birds around other than the usual suspects in an around the pond. On the well-manicured lawn right by the pond an immature Ring-billed Gull was relaxing. It did not seem bothered by my presence. Although gulls are common they can be notoriously difficult to identify and entire books have been dedicated to telling one gull species from another. Their plumage change as they age and there is a great deal of variation within species and often little variation between species. Hawrelak park usually has a large contingent of Ring-billed Gulls, so it is likely that any gull found in the park is one of those… except that this individual does not look like a typical Ring-billed Gull. Although the bill has black on it, the black ring on the bill is noticeably absent and the rest if the plumage is completely different from a Ring-billed Gull. It turns out that this individual’s plumage and bill is the look that juvenile Ring-billed Gulls sport. The typical look of a Ring-billed Gull is known as the breeding plumage and it takes the gull three years to reach it, with its appearance changing with each fall moult.
