The Northern Fulmar is a petrel that lives in the northern oceans, across the Atlantic and Pacific. It is abundant in Alaska and the Canadian Arctic, but few people ever see them there as they tend to breed in remote places. In contrast, around Iceland, the Faroe Islands and British Isles they have undergone a spectacular increase in their population in the last two centuries and they are commonly seen as a result. They are one of the longest-lived birds, with an average life span of about 32 years. In Scotland, birds that were banded in 1951 were still found breeding in 1990 at ages likely greater than 50 years!

It is similar in appearance to a gull, but stockier with a thick neck and more rounded wings. They have a short, thick bill, with a little tube on top. Fulmars come in many different colors, referred to as light morph, intermediate morph and dark morph, but also in every gradation in between. There is no generally accepted explanation for this variety.

Here is a picture of a dark morph Northern Fulmar:

A few months ago we were asked by the Saskatchewan Burrowing Owl Interpretive Centre if we could provide our Burrowing Owl coloring page to be included in their resource material kit. Naturally, we were very happy to oblige! The Centre kindly sent us this photo of a rather impressionistic coloring sheet making an appearance alongside some young visitors and a very special guest, George the Burrowing Owl.

Today's featured t-shirt is this funny Who are you calling Harpy? design with our Birdorable Harpy Eagle. A Harpy is a mythological Greek winged spirit known for stealing food. The Harpy Eagle is named for this mythological animal, but the word harpy is also used to describe a predatory person, or more commonly, a shrewish woman. Most women would probably not like to be called a Harpy, but fans of the amazing crested bird of prey probably don't mind. Our cute Birdorable Harpy Eagle stands here with the funny phrase "Who are you calling Harpy?"
