Big Birds In Flight
Extremes In Fish Size White Pelicans Will Attempt To Eat
A Few More Birds (and a personal observation) From Our Recent Montana Camping Trip
This post is largely a collection of photos that documents some of the bird species I photographed on our recent camping trip to southwest Montana. Most of these images have flaws and as I’m prone to do I’ll be pointing those flaws out but for me each of the images has something positive to offer to make up for their shortcomings.

White Pelican Stretching Pouch in Flight.
American White Pelicans are known to do some pretty strange things with their pouch – one of them is pouch stretching (I’ve been unable to find an official term for the behavior). A four year old image – I no longer have the original file so can’t access exif data They pull their head back and force their very flexible pouch down over their neck and upper chest in a process that looks, well.. bizarre. I don’t think this behavior is particularly unusual as I’ve seen and photographed it several times. According to Birds of North America Online the function of this display is “uncertain”. Canon 7D, 1/5000, f/6.3, ISO 500 However, these birds are also fully capable of pulling the bottom of their pouch up above the level of the lower mandibles without having to pull the pouch down over their neck. I don’t fully understand how they’re able to do this since the pouch itself is non-muscular. Internet research on the subject has been unproductive. I assume there must be some form of bony or cartilaginous rod that extends from the throat area down the middle of the bottom of the pouch about half way to the tip of the bill. With muscular control of the base of that extension in the throat area they would be able to raise the bottom of the pouch above “horizontal”. I’ve seen them do it twice – the first time without a camera while the bird was perched. But the second time, a couple of weeks ago, it was done in flight which…
