Just a few miles south of our park is Arcata Marsh, an interesting collection of large fresh water and salt water marshes/ponds/lakes located in the Pacific Flyway.
The technical name of the place is Arcata Wastewater Treatment Plant and Wildlife Sanctuary.
Ummmm, those “fresh water” ponds/lakes are actually waste treatment areas….but that’s a story for another day.
The fresh water areas are constant in their water levels, but the salt water areas are completely transformed by the tides four times a day…from a very large bay to mud tidal flats and grassy fields.
Fresh and salt water attract different groups of waterfowl, and high tide tends to attract different birds than low tide.
We spent low tide the other day with some Willets and Marbled Godwits…at least that’s what I think they were.
Although they frequently forage one by one, we’ve noticed these two types of birds usually hang in quite large groups….and then they do the hey-everybody-turn-and-look or the skittish let’s-all-fly-at-once.
