I was out this AM with my dog and a huge flock of birds suddenly flew overhead and most landed in my neighbors front yard tree. Took some photos with my cell phone, but couldn't verify what the birds were - I 'suspected' Cedar Waxwings, but couldn't be sure. Hurried home and grabbed my Canon 80D with my Sigma 150-600mm Sport lens. The basic photo conditions were terrible - misty/foggy, dark gray sky, and the birds were all up high in the tree against that sky! I consider these "record" shots, nothing special. First 2 were taken with my cell phone, the last 3 with the 80D. Oh, and I was about 80-100' away.
Congratulations on your "record", I know exactly how you feel because I too remember the first time I shot cedar waxwings. They have such beautiful feathers especially in bright sunlight. Thanks for posting.
