Whimbrel - 17 Jul 2010


I gave Will Weber a call as I arrived at the Middle Creek entrance to Pt. Mouillee SGA this morning at 9am. He had been here since ~7am so I was anxious to hear if anything interesting might be there. As we spoke he was on the Middle Causeway at the west end of the soybean/ sunflower/ cornfield scoping the three Plegadis ibises and he urged me to come directly.

I stopped near the pump house just long enough to grab a couple of photos of the American Lotus that was growing and blooming in Mouillee Creek. I bypassed several digiscoping opportunities (Bank Swallows, Indigo Buntings) and headed directly to the Vermet Unit where I found Will just beyond the crop field.



The ibises were in view approximately 100-120' away and at the edge of any useful digiscoping opportunities. Will provided a terrific writeup on his blog site with observations and photos regarding the suspected hybridization (Glossy X White-faced) of at least one of the birds. I managed a couple of keepers, but the rising temperatures and moisture in the air produced a lot of distortion. Still, I could make out the red eyes on the smaller of the two birds and the brown eyes on the (presumed) pure Glossy ibis.




I did not get good looks at the third bird until it flushed and headed south into the Lead Unit with the other two. Two of the birds showed primary molt, while the third bird showed no molting feathers.


No sooner did we head for the Banana Unit that a Whimbrel flushed from the crop field to our left. I managed a couple of flight shots as it took off just a few feet away and we watched it land in the road ~150' ahead of us. We scoped the bird as it fed on bees and walked briskly away and then followed it toward the Banana Unit where it flushed again and flew back to our left and landed back in the crop field.



I was able to get a couple more digiscoped images before it hunkered down in the vegetation.


We were disappointed to find that Cell 3 was completely submerged under water with only a tiny spit of mud occupied by Ring-billed/Herring Gulls and a few Caspian Terns. Unless the water is drawn down there'll be no habitat available for migrating shorebirds. I stopped on the way out to photograph a few of the many Blue Dasher dragonflies hovering and resting on the numerous knapweed plants lining the dike. One photo was even sharp enough to resolve individual eyeballs of the compound eye.





Several Black Swallowtail butterflies were nearby, as well. I was able to grab numerous photos of one cooperative bug. Cabbage Whites were numerous, but none would light onto plants for pics.


We scoped the Humphries (Lead) Unit but found nothing of interest. The Vermet Unit held several large concentrations of Great Blue Herons / Great Egrets, but little in the way of shorebirds (other than a few Lesser Yellowlegs and a Solitary Sandpiper).

Returning to the Middle Causeway via the Vermet/Long Pond trail we saw a few Indigo Buntings, Least Sandpipers and Killdeer, but nothing worth stopping for. We returned to the cars at 11:30 am as the winds and heat picked up.
