My family and I return regularly to Bozeman and other parts of Montana for mountain getaways. I figured I might as well start collecting birds from that area, too. Some of this set were shot with a Tamron 150-600mm supertele, and more recently with a Canon 100-400 L ISii. I did some learning on the fly, so to speak, and had some success after a little early fumbling. It turns out that tracking a bird on the wing at 600mm is a bit like looking through a drinking straw. As the 600 is very heavy, I didn't carry it on all outings. Some photos were shot with the Canon 70-200 f/4 L.
