Yesterday morning I spent time focusing on photographing Great Blue Herons on the frozen marshes of Bear River Migratory Bird Refuge.

The Great Blue Herons seemed to be on the edges of the shelves of ice and water that has opened up because of the milder days we have had recently, they congregate there because they can capture fish in the open waters.

Some of our wading birds including our Great Blue Herons stay here for the winter despite the harsh conditions that we have in northern Utah during the coldest part of the year. When the water freezes completely over the herons start to hunt for small mammals instead of fish.

This Great Blue Heron seemed to be warming up in the sunlight. It may have fished for breakfast before I had it in my viewfinder or it may have been waiting until it warmed up before it started to hunt for prey.

I decided yesterday morning that I also wanted to take photos of the Great Blue Herons that showed more of the frozen marsh, the wintry habitat and the mountains beyond the marshes so I pulled out my Nikon D810 that has a 18-200mm lens attached to it.

Photos like this one and the one above show much more information about the habitat and the harsh winter conditions than a photo taken with my long lens can. I think it is important at times to visually take a step back and show the habitat my birdy subjects are found in for the story about the images to be complete.

I saw a low of 20 degrees at the refuge yesterday morning but by the time I left the auto tour route the dark, dirt road had defrosted and was slick and muddy.

I know that I have written before that our Great Blue Herons have to be tough to get through our hard winters here in northern Utah and I believe these photos that were taken yesterday morning show just how strong they have to be to survive the harsh winter conditions.

Life is good.
