Sanderlings - 28 May 2024

I patched the front tire of the bicycle yesterday and it appeared to hold so I headed down to Pt. Mouillee SGA this morning before wind / rain were expected. My plan was to check out the Walpatich Unit to look for Glossy Ibis (continuing) and then to Cell 3 to look for shorebirds.

Arriving at the Mouillee Creek parking lot at 7:30 am I took the bike out on the Middle Causeway and headed to the north end of the Walpatich Unit. There I turned north and headed to where I saw the ibis pair a few days ago. As I arrived a small squadron of 6 American White Pelicans flew overhead with the idea to join another pair of birds in the open marsh but decided to head south toward the Humphries Unit. 

I scoped the Walpatich Unit from the SE corner but failed to see any evidence of the Glossy Ibis pair. Instead I found a nice mix of Dunlin (24), Semipalmated Sandpipers (30), Semipalmated Plovers (23), and 4 Whimbrel! I was able to digiscope them from the middle dike.

Other nice finds were several Wood Ducks, a pair of American Wigeon, and several Blue-winged Teal.

I continued north around the north side of the Laughtenschlager Unit then backtracked south along the east side. Along the way a Willow Flycatcher flew in and provided a few pics from the bike.

Swamp Sparrows and Marsh Wrens were singing loudly as I rode. The Laughtenschlager Unit was empty except for a pair of Trumpeter Swans that announced their presence with loud trumpeting and wingbeats. I managed to stop the bike as they flew toward then past me.

With winds now blowing steady at 20 mph from the SW my ride to the Banana Unit was relatively easy. I headed straight to the NE corner of Cell 3 where I was able to hop the ditch and walk out onto the soft, cracked-mud flats to get closer to the shorebirds. A small patch of phragmites allowed me some cover so I could scope the exposed mudflats and large pond that held dozens of American White Pelicans, Caspian Terns, Forster's Terns, and Canada Geese.

As I began scanning the shorebird flock I spotted one, two, twelve, twenty, forty-plus Ruddy Turnstones scattered along the shoreline. As I counted them I spotted a Willet, then five Red Knots, and the first of three dozen Sanderlings among even more Semipalmated Sandpipers and 100+ Dunlin.

Winds were blowing steady directly at me, and distance from the shorebirds removed any motivation to digiscope birds. However, when a small flock of Sanderlings and Semipalmated Sandpipers landed a few feet away from me I relented. Semipalmated Sandpipers included a mix of birds molting into breeding plumage and birds still in basic plumage.

A few Sanderlings wandered by and allowed some digiscoping to show their breeding plumage.

I made another scope sweep of the shorebird flock next to water and managed to find another 3 Whimbrel on shore and six Northern Shovelers among a dozen Gadwall in the water.

Another flock of shorebirds flew in and landed nearby so I turned the 200-600mm f/5.6-6.3 lens on them. More photos of Semipalmated Sandpipers and Sanderlings resulted.

The high winds were now bringing rain so I headed back to the back and rode south to the beach area opposite Cell 3. There I found a single Bonaparte's Gull and a small group of Ruddy Turnstones that were close enough to photograph. Another 18 Ruddy Turnstones would fly by as I rode back to the car.

The ride back to the car was uneventful. The Middle Causeway was relatively quiet and I spent my time pushing against the 20 mph winds that were slowing me down. I'd return to the car by 10 am and head home.
