A pair may have 2 or more alternate nest sites, using them in different years.
Nest built by both sexes a bulky platform of sticks, lined with weeds, grass, leaves, moss. New material added each year, and nest may become huge. Learn more about these drawings. Northern birds are migratory, mostly moving late in fall and early in spring. In western United States and southwestern Canada, many adults may be permanent residents, but young birds may migrate south in fall. In the broadest and most detailed study of its kind, Audubon scientists have used hundreds of thousands of citizen-science observations and sophisticated climate models to predict how birds in the U.
The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. Each map is a visual guide to where a particular bird species may find the climate conditions it needs to survive in the future. The colors indicate the season in which the bird may find suitable conditions— blue for winter, yellow for summer breeding , and green for where they overlap indicating their presence year-round.
The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there.
The outline of the approximate current range for each season remains fixed in each frame, allowing you to compare how the range will expand, contract, or shift in the future. The first frame of the animation shows where the bird can find a suitable climate today based on data from You can play or pause the animation with the orange button in the lower left, or select an individual frame to study by clicking on its year.
Bullet fragments routinely poison California Condors. With cooperation from hunters, the ban could be a turning point for the endangered icons.

Climate Endangered. This magnificent bird is widespread in the wilder country of North America, Europe, and Asia. About the same size as the Bald Eagle, the Golden is less of a scavenger and more of a predator, regularly taking prey up to the size of foxes and cranes. SmartNews History. History Archaeology.

A golden eagle finally appeared at It landed on the carcass, but only stayed for a moment, never stepping off the deer. That was it for that day.
I returned the next day with one of our bald eagle nest-monitors, Kathy Maloney. We again set up all the traps before dawn, and watched a golden eagle fly by, but the bait was ignored the entire day. The goldens were still around, but the farmers told me that when the birds fed on the deer carcass they tended to stand on it.
So we decided to try a rocket net. I built a mock-box a box that looks like the rocket net box to get the birds used to having a box on site.

I placed a fresh carcass on a flat area in a field about yards from the road, which would be in range of the radio-controlled detonator switch for the rockets, and set the mock-box out too. On January 29th, Pete and Mike Clark arrived at the farm well before dawn and we set the rocket net up. We used my jeep as a blind. I had a good visit with the two guys that day, but the eagles never showed up.
On February 5th, I checked in at the farm to see if the birds were around, and found both feeding on what was left of a wild turkey carcass out in the fields.
A flock of over turkeys winter on the farm, picking grain out of the manure that the farmers spread on the fields. In fact, that is probably why this pair of golden eagles winter in the area-- turkey dinner. So now I knew what I had to get for bait. I spread the word far and wide to have folks pick up any road killed turkeys they came across. Unfortunately and surprisingly, that first turkey carcass was a long time coming.

In the meantime, I decided to try one of the cottontail rabbit carcasses I collected. On five different days between February 12th and 26th, I wired a rabbit carcass to a bag of rocks buried in the snow. I also attached the leghold traps to the rocks, so any trapped bird would be held in place. One thing that all five of these days had in common was the cold. Each of the mornings was below zero except for the one balmy 8 degree morning. The site I used was near where we set the rocket net up.
I used my jeep as the blind rather than the farm office. At least the heater worked! I had company on one day, bald eagle nest monitors and photographers extra ordinaire Lou Buscher Jr. The other days were spent reading books as I waited for action. I saw the eagles each day, but never had any luck getting them to the bait.

I was getting desperate! Finally, on February 28th I obtained the first of several turkey carcasses. I placed one at the original bait site and the eagles found it fast. On March 3rd, I set out a new turkey and the traps, now beginning day 9 of trapping. I was joined by my co-worker, Liz DeJoy.
Shortly after , we had a golden eagle on the bait! I watched it feed for an hour and a half, but my heart sank when it flew off!
