Have you seen the large flocks of white ibis (Eudocimus albus)heading north? I saw three Vs yesterday, all going back to the Eastern US for the summer. Ibis are the medium-sized white birds with the bills that curve downwards. They like the marshy areas along the Rio Presidio. They are monogamous and live in large communal groups. I think it is the ibis who dig up the turf on the golf course in the evenings looking for grubs and other subterranean insects.
The Yellow Crowned Night Herons (Nycticorax nycticorax) will soon be nesting in the almost dead tree near the 1st green. This photo is of a male mating display. Both parents build the nest, incubate the eggs for 3 weeks and feed the chicks so you will be able to observe them hanging out in that tree for a while.
Just so you know, a mourning dove (Zenaida macroura) is thinking about nesting in the philodendron on the exit end of the tunnel between the 1st green and the 2nd tee box. Last year, she nested at the entrance end of the tunnel between the 8th green and the 9th tee box. When you would walk into that tunnel, she would flush and scare the daylights out of you. She is much better situated in the first tunnel because she can flush away from your approach. Mourning doves are the #1 game bird in the US with over 70 million birds shot annually. Luckily for them, they are extremely precocious and can raise up to 6 broods a year. They can fly at 55 mph so you have to be a pretty good shot to bag one.
