As we rounded the second official week of the spring waterbird count the signs of spring continue to show themselves. This is indicated by the disappearance of much of the ice along the shoreline and the influx of waterbirds taking advantage of these open waters. This was noticeable on the first day of this count window, April 22, when a Long-tailed Duck and a Red-necked Grebe, as well as several Red-breasted Mergansers, Horned Grebes, and Common Loons were sitting out on the water that morning. However, while a noticeable morning flight and raptor flight occurred overland, a flight over the water was muted in comparison. More easterly winds the following morning of April 23 would produce better conditions highlighted by 48 Northern Pintail and 32 Greater Scaup counted in a moderate waterbird flight.

This would just be a teaser what would come the following morning of April 24 were a diverse flight of waterbirds occurred. Most individuals were recorded heading back to the southeast past the point. The most abundance species in this flight was the 320 Green-winged Teal. One flock of 82 individuals was observed which include included several other species, including both Scaup, American Wigeon, Blue-winged Teal, and a drake Wood Duck. A pair of Canvasback also passed by the point heading southeast, a scarcely observed species on the spring waterbird count. Another highlight of the morning was a Wilson’s Snipe following the same flightline as the ducks out over the lake!

While overall numbers were down from the previous morning on April 25, alternate counter Jack Kew still made what started out as a foggy day quite productive. Jack nearly broke 100 Northern Pintail with the 98 he observed as well as detecting the first Peregrine Falcon and Palm Warbler of the season for the count. We have almost as much fun counting other species as we do waterbirds here! Fog was once again present on the morning of April 26, and overall waterbird numbers did take a hit as a result again. However, Sandhill Cranes made their biggest push in a few days with 350 individuals observed. The same adult dark morph Swainson’s Hawk that had been observed previously earlier in the week was observed once again once the fog lifted and raptor lifted off over the point. 

 

While waterbird numbers were moderate overall diversity was decent on April 27 with species ranging from Northern Shoveler to White-winged Scoter being observed. However, it was the flight over the point that garnered my attention at times. Sharp-shinned Hawks were going before sunrise and from the Waterbird shack alone I tallied 1053 individuals during the duration of the waterbird count. Also a note was a female of the Prairie subspecies of Merlin first spotted by Sean before seen from my position making the jump off the tip of the point. The passerine morning flight was intriguing as well with good numbers present of many species such as the 124 Black-capped Chickadees, 131 Purple Finches, and 440 Common Grackles observed. Purple Finches are another species that often will circle high above the point during morning flight.

Another good water bird flight ensued on the final morning that this blog post covers, April 28. A low pressure system moving through overnight paired with southeast winds at the start of the count produced good conditions at the site. The highlight of the morning 231 Greater Scaup, the high count for a single day so far this season. Several other species of dabblers and divers passed by as well with the most interesting being two separate pairs of Gadwall mixed in. Despite the rains overnight, it was apparent that passerines still moved with several species coming in off the water throughout the morning. It seems shifts to lower pressures seem to be the pressure change that induces bird migration in the spring.

 

There wasn’t a dull day over this recent count period. As we head into the coming days, we hope this continued northwest wind doesn’t completely halt bird migration for the time being. But maybe it will just be the catalyst to back up enough birds that can lead to some impressive flight days once the winds do finally shift. Only time will tell.
