Today I am sharing some birds we find foraging around the shore of our lakes, ponds, rivers, and sloughs. Some of these birds can be found here in the Sacramento region year-round but most are much more prevalent from late autumn to early spring.

The wildlife refuges in Northern California are one of the wintering over spots for our two varieties of wild white geese: The Snow Goose (Chen caerulescens) and the Ross’s Goose (Chen rossii). They are 2 species that look almost alike and hang around together. In fact they do inter-breed so hybridized geese can be found. There is also a darker morph of both species which can sometimes be found in the flock. The darker or “blue morph” of the Snow Goose is sometimes called a Blue Goose. The head of the Ross’s Goose is smaller and more rounded than the that of the Snow Goose. The Ross’s Goose has a gray patch at the base of its bill. The Snow Goose has dark smile lines on the side of its bill that, I think, look like teeth.
It is amazing site to see these birds lift into the air. Entire fields full of geese will take off at one time making it look like a blizzard of white. On the day we observed them we were treated to an air show by many flocks. Thousands of birds were flying in large “V” formations as far as you could see in all directions. It was amazing!

Last week we made the first of our pilgrimages to a spot where Sandhill Cranes winter over. It is still early in the migration and there seemed to be fewer there this year. I caught these images just as the last rays of the sun were setting over Mt Diablo.

Living along the Pacific Flyway provides a treat; many birds pass through or winter over around here. Our most well known and popular of the winter visitors is the Sandhill Crane. But, in this post, I am going to present another visitor, one less known, the Cackling Goose (Branta hutchinsii).
The Cackling Goose and the Canada Goose look nearly identical and they are related. Until recently they were considered 2 subspecies of a single species. The Cackling Goose is smaller and makes a distinctive cackle instead of the Canada Goose’s honk. One of the field marks I use to identify them is a white band at the base of the black neck; its not a perfect identifier but it is very good.
While the Canada Goose is ubiquitous year around, I have only seen the Cackling Geese, reliably, in a limited area and only in Late October and November. One birder told me that we get the Aleutian Subspecies; there are several other subspecies.

I’ve produced my first set of images in false color infrared. Most infrared pictures I see are in black and white. But my camera can also capture some visible light; not all, just some. So, I can get some interesting effects. I still haven’t fully grasped what it means to shoot heat as well as light. A goldfinch facing the sun will give me some yellow in its breast but facing away from the sun, I lose the yellow. A red car became bright orange. A blue car became darker. So, still much to learn.
In a blog I follow and enjoy, Peace of Life Today, the author shared the post “Just A Duck” which contained some beautiful photos of a female Mallard. Until a few years ago, that is what they were to me. I could identify a white domestic duck and a male Mallard. I have heard people talk about a variety of ducks, but they were just some abstract concept. Then I met some new friends who were wildlife photographers. They taught me that we live in the Pacific Flyway, a migration route and wintering ground for many species of waterfowl. They, along with other birding friends, taught me about Mergansers, Golden Eye’s, Teals, and many more. The diversity and beauty of these creatures is astounding. For me, there is no such thing as just a duck anymore and I am better for it.

I am sharing some images of Great Blue Herons (Ardea Herodias) that I’ve taken over this summer.
The heron in a tree looks out of place. I normally see them foraging along the water’s edge. But they are comfortable in trees. In fact, they nest high up in trees.
