After the Leaves Turn
After the leaves change color and before the heat of mid-summer burns, weeks, months and whole seasons can be tracked by the behavior and movement of birds.
When snow storms pummel alpine and subalpine areas of the Western Mountains, Rosy-finches such as this Gray-Crowned Rosy Finch wander downslope to places where seeds can still be found.
The arrival of Boreal Chickadees heralds the arrival of winter in many northern states, as several boreal species move south to survive the winter.
Shrikes are like time-share owners, with Northern Shrikes replacing Loggerhead Shrikes in many northern parts of North America, until each species moves still farther north to breed.
This loggerhead shrike hunts from the thorny bush that will later protect its nest and young.
When the bubbling echoing calls of Greater Sage Grouse greet the dawn at traditional lek sites, surely the snow is receding and spring is around the corner.
The melodic call of the Meadowlark heralds spring throughout North America and reminds us why so many states have selected it as their state bird.
Great Gray Owls can be extremely nomadic, wandering south or to lower elevations in winter. By the time spring has arrived, these ghosts of the northern forests might me on nests hundreds of miles away from their winter haunts.
