I spend about 3 months a year durng the winter months in San Jose and walk the estuary path 4-5 times a week photographing birds and whatever else that I find interesting. I've attached a representative bird photo from my 3 walks as examples. The great thing about bird watching in the estuary is being able to see both water & land birds as you walk from the El Presidente Hotel towards town. It's common to see a variety of water birds that include herons, egrets, ducks, grebes, coots, kingfishers, sandpipers, frigate birds, pelicans & many others in and around the water. Further up the path as the landscape gets drier you can see a variety of warblers, wrens, orioles, scrub jays, woodpeckers, flycatchers, cardinals, buntings, grosbeaks, osprey, kestrels, red-tailed hawks, kingbirds, hummingbirds, doves, verdins & many others. One of my favorite is the male Vermilion Flycatcher that hang out on the fence around the corral. What's good about the estuary is being able to see such a variety of birds any time you walk. The bad part is seeing how poorly the estuary is maintained by the local goverment. I have met many Mexicans who love and cherish the estuary and are just as frustrated that the local goverment is not more strict in policing this area for garbage and littering. Speaking of "policing", the estuary is a very safe place to walk and is relatively free of bugs during winter months. I have taken many marvelous photographs during my many walks and enjoy sharing the best with friends & family.
