Whimbrels in the area, most of them flying in at dusk to join a roost at the refuge. March is the month to look for migrant Ruffs, early May is the time when Curlew Sandpiper and Black-tailed Godwit have been found. These numbers persist through October, at which time the flocks settle into their typical winter mix. Winter numbers can be astounding as well. At sunrise at sundown, the flocks of ducks, geese, ibis and shorebirds leaving and returning to the roost in the middle of the refuge are impressive, to say the least.
Winter is also a good time to check the surrounding treelines and grassfields for landbirds.
