Artificial intelligence and bird identification

Sharpen Your Skills and Help Train Merlin™.

A project of the Cornell Lab of Ornithology, this site shows you a bird and asks you questions for identification.  By so doing, Merlin begins to “learn” what people need to know. To build Merlin, Cornell Lab needs to know how thousands of people remember and describe birds.

Two weeks from the day . . .

Canon returned my 100m-400m lens this past Friday, which it repaired under its warranty, shipping it via standard overnight delivery–all at no cost to me.  I sent the lens to them via ground on the Friday two weeks prior. It turned out that the image stabilization was not working properly.  They repaired the unit, and checked and cleaned the rest of its inners. I’ve had a chance to use it and it now seems to be working fine.  Bravo Canon!

Image destabilization

It seems I’ve run into a problem with the 100–400mm lens that I purchased this past June.  The image in the viewfinder began jumping around when I pressed the shutter button half-way—often this would continue even after shutter release.  I contacted Canon’s customer service. Based on my description of the problem they suspected the image stabilization had failed.  I sent the lens to their service center and they accepted the lens under warranty. I hope to have it back in about another week.  I’ll let you know how the process went, as well as how the lens works when I get it back into the field.
