Last week, my wife and I enjoyed a brief holiday with my family on Terschelling, a Frisian Wadden Sea island off the coast of Fryslân, the Netherlands. With its quaint little towns, historical lighthouse and (by Dutch standards) large surface of nature reserve, I find it to be one of the more beautiful Wadden islands. Like the other islands, its salt marshes, meadows, dunes, forest and heath fields, along with the unique intertidal mudflats of the Wadden Sea provide an extremely important site for many species of migratory, wintering and breeding birds. An estimated 12 million(!) birds use the Wadden Sea area every year, so it’s not surprising that the UNESCO has listed it as a World Heritage Site.
Although it was too early for the peak of spring migration, we found plenty of gulls, of various species, on the beach. Gulls might seem somewhat boring or even a pest to many people, but they are (at least to a biologist) really interesting species. Few people realize for instance that the black-headed gull they see eating discarded fries from a garbage bin during the winter, might be found breeding in a marshy area in Estonia a few months later. So although many Europeans see black-headed gulls in their cities year-round, depending on when they see them, they might be of very different “nationalities”. The northerly breeding populations are all strictly migratory, whereas populations found more to the south might consist of year round residents. As such, gulls from different countries might cross paths in the winter season.
After two long posts featuring panorama and cropping techniques, today a short post featuring long legs.
Now you have to admit, that’s a lot of leg! What you see is four foraging Black-necked Stilts. Relative to their body, their legs are extremely long and only topped by flamingos, so their name fits them rather well. The two in the front are males and the two in the back, with the more brownish mantle, females.
The Black-necked Stilt is usually found in the shallow waters of mudflats, estuaries, lakes and other types of wetlands. There it feeds on vertebrates and small fish that live in and on the soft substrate. As with many so-called shorebirds, the long legs come in handy when wading through the water, keeping the rest of their body dry.
This crop is about 20% of the original, shot with my D300 and the 70-200mm, at 2.8. With this lens I had to be quite close. Rather than chasing the birds, I just waited at a good spot. Once the birds got used to my presence they came foraging very close to me. Although the afternoon light was a bit harsh, I felt that the nice line-up and their reflection made up for most of it.
From stitching big to cropping small: Where the images in the panoramas of my previous post featured a multitude of the MP (Megapixels) found in normal dslr images, today’s image, a female Costa’s Hummingbird, only has a fraction of my D300’s 12.3 MP:
To crop or not to crop
This image is a 22% crop, which means that it’s only 2.7MP. As you can see, even such a significant crop still produces an image that’s usable for web purposes. Some photographers try to convince others that cropping is bad. They think that you should just frame the image right from the start. While I agree that it would be ideal to do so, often it’s not only difficult, but simply impossible. Continue reading →
Although I have a few articles in the works, I still haven’t been able to finish and post them. So here just a quick message to let you know that I’m still trying to find time to finish editing. Once work settles down a bit (in two days) I promise to get the first one online.
So keep an eye out for new posts. Expect articles on panorama photography, effects of perceived danger and a tutorial on composition, in which the burrowing owl seen here will feature as a model.
