My first year birding, I took a picture of a Empidonax flycatcher that I wasn't able to identify. Although I felt discouraged by this at the time, I have now learned that their identification is among the most difficult for birders. It is so difficult, in fact, that the bander of this bird had to use a mathematical formula to confirm its identity. This involved comparison of the ratios of and differences between measurements of the bird’s body parts (bill length and width, wing length, tail length, etc).
