Yes, there will be more. I found that the bords were generally not as tame as is made out, certainly I had to use some stealth to get as close as I did to the heron (most tourists tower over the birds, compact out at full stretch, and off flies the bird!). Luckily in this case we were on a beach, where you can wander at will and take you time. The boobies were the least disturbed of all the birds, sitting right next to the trails, unmoved by tourists.
The Sea Lions too were unmoved by people, even with babies a day old. Swimming with them was a real experience!
Lots more to be processed yet!
