Math and Magnification

Parked on the shoulder of the cutoff road under the Intracoastal Canal bridge, Bill Maroldo was working on a Great Blue Heron on his side and I had a nice Little Blue Heron perched on a post on mine. We had some sea fog so the light was nice and there were no crabbers to disturb the birds. Bill suggested I might like to use his 1.7x teleconverter instead of my 1.4x on my long lens.

You can already see where this is going, I bet. 

Working for Warblers

All birders and bird photographers look forward to Spring Migration when flocks of tired and hungry warblers land on our coasts. Many leave the Yucatan at dusk and fly the 600 miles straight across the Gulf of Mexico to arrive 11-14 hours later.
