Arrived at about 8 AM. Some good reports have been coming out about this venue, however it can be challenging to hike in here. Lots of mud, standing water and biting insects. I didn't identify any of the marsh wrens, sedge wrens, nelson's sparrows, saltmarsh sparrows or clapper rails, but did see large numbers of American Avocets, Black-bellied Plovers, American Wigeons and an American Bittern. Least Sandpiper, American Robins, some Flickers and lots of Palm & Yellow-rumped Warblers.
