From my trip down to Bernardo & Bosque I decided to pay more attention to the photos and especially where I got a lot of BIF keepers compared to where I got only a few BIF keepers. I noted the percentage of keepers with two birds was much smaller than a lone bird but I was really surprised with how few I got with 3 or more birds. Below is a guess using 40 as the starting number.
40 Potential Keepers of 1 bird
15 Potential Keepers of two birds
2 Potential Keepers of 3 or more birds
Here ares some 3 or more shots that I kept. When I was going thru the photos I decided if I keep one it has to show the head on all the birds in the photo.
