Too many stories to tell from a day’s birding. So this post will be to prove to myself that my statements on migration and shorebird turnover are accurate.
To prove the point, I visited the local shorebird spot Friday PM, Saturday AM, again Saturday after the passing of the Cold Front, and Sunday morning.
Luckily I was mostly correct and there was turnover in shorebirds.
On the Friday Evening’s and on the early Saturday AM visits the BLACK-BELLIED PLOVER was still present from last weekend along with some SEMIPALMATED PLOVERS which had arrived earlier in the week.
But the number of KILLDEER from Friday to Saturday had dropped from 100 to around 10. Did they fly in front of the front or go somewhere else locally?
The Cold Front came through around noon Saturday and on the afternoon visit the Black-bellied Plover was gone. Killdeer numbers were still low but there were now LESSER YELLOWLEGS and PECTORAL SANDPIPERS present. This was still the case Sunday.
So a passing front does lead to shorebird turnover.
Even though the forecast was for heavy rain Saturday I headed out anyway. I follow the old axiom to “Bird in the worst weather”. And I’m glad I did.
After leaving the shorebird site I headed to Driftwood SFA and then on to Johnson County Park. My goal at those locations were birds that will be leaving soon. But that will be the next blog.
Just before I arrived at JCP it started to rain. I parked by the small pond and did a quick check for shorebirds. Nothing.
Fast forward to an hour later and I’m still sitting in the car at the same spot watching the strong thunderstorm end. Putting the window down I hear the “peek-peek” of a SPOTTED SANDPIPER.
Not only had the storm forced down the Spotted Sandpiper but a dozen SOLITARY SANDPIPERS.
I have experienced this a couple of times previously. During migration if there is a Cold Front coming through and there is a strong storm, immediately go out and check flooded fields, shorebird spots, etc. The odds are there will be grounded shorebirds that won’t be hanging around long.
I didn’t see anything uncommon but one never knows.
A late weekend addition. Sunday night I watched 4 COMMON NIGHTHAWKS feed in the neighborhood. These must be migrants following the Cold Front since the only one seen in the neighborhood this summer was in late July.
