For The Love of Pelicans: Gular Pouch Show

I have been looking forward to sharing this amazing sequence of photos. This photographic technique is what I like to call “laying on the shutter.” :-)

I’ve talked before about the American White Pelican‘s (Pelecanus erythrorhynchos) gular pouches. These gular pouches are vital to the pelican’s ability to capture food – so it makes sense that they take very good care of them.

According to this range map, many Americans have an opportunity to see these “wow” birds:


Range Map Compilers: NatureServe, 2002; WILDSPACETM 2002

Global Range: >2,500,000 square km (greater than 1,000,000 square miles)

Global Range Comments: BREEDING: locally, now primarily in Prairie Provinces (Alberta, Saskatchewan, and Manitoba), also adjacent eastern British Columbia and western Ontario, south through California, Nevada, Utah, Colorado, South Dakota, and Minnesota; also coastal Texas and coastal Tamaulipas; sporadically in Durango, Mexico (Johnsgard 1993, Evans and Knopf 1993). Over half of the breeding population nests in Saskatchewan and Manitoba. NON-BREEDING: Florida, Gulf of Mexico coast to Tabasco and Yucatan, and central California south to southern Baja California and west-central mainland Mexico, sometimes south to Guatemala, Nicaragua, and Costa Rica (AOU 1983, Evans and Knopf 1993). In North America, the highest winter density occurs in southern Texas (Root 1988); other important areas include the Gulf coast and Everglades region of Florida. In summer, sometimes wanders north of usual range.1 2 3

I’ll leave you with a video that I saw a couple of years ago.  At the time, I was aghast, but now I find it more fascinating than anything else. Fair warning – this is is footage of a very rare occurrence of a pelican eating a pigeon!

    This sequence of photos is amazing! I will need some interpretation from you later on to describe what is actually happening in some of these photos.
    WOW!
