Late report,
At the entrance pond to my neighborhood west of Larkspur (Douglas Co), they're dredging to remove sediment so that it will hold water as it once did, keep the evil cattail marsh from further encroachment, etc.
On March 7th I saw a Greater Yellowlegs foraging there, right in the midst of heavy equipment and practically getting run over. My thought was that it was getting a rich food source from the over-turned sediment, I think they typically feed on small invertebrates and fish but this one was stabbing the very black mud as if on a mission and walking two feet up the accumulated piles to feed. Made me wonder what soon to be arriving shorebirds might find in the areas of Chatfield where similar (massive scale) exposure of sub-surface sediment is occurring.
