Friday, March 24 produced the best longshore flight of the season. Without final Grube Magnitude Index numbers, the total diversity and abundance alone is enough for us to be fairly confident in today’s flight. This time the weatherman was right on. Warm temperatures overnight brought a decent nocturnal flight, and the same continued southerly gusts kick started a good morning flight. The gusty south winds were too much for the counters to be elevated on the platform, but with the winds keeping many birds close to shore, the nearby staircase worked well today to count nearly 12,000 birds (11,743 to be exact). Today’s 70 species was also the highest of the season.
The radar loop from 1am to 7am showed a good nighttime movement, despite early rain that fell shortly after dusk. April and May radar signatures will develop higher dB values later in the season. Counters were on scene before dawn today to get an early sense of how the morning flight would flesh out. With sunrise not even upon us, fast moving flocks of blackbirds, mainly grackles, were already utilizing the pre dawn light to begin an exodus north. Many flocks riding the strong winds like a buoy floating over waves in the lake.
Blackbird and robins flocks were literally using every flyway we observe near the tower. Some were traveling high and fast both east and west. Many west bound flocks were trying the low route that would take them dipping through the west lot, and then swiftly rising at near eye level to the counters. Another pathway brought birds just south of the tower site in similar streams.
As arrival dates go, today was pretty darn good. Overall, over a dozen new birds for the season were logged today. The list of new arrivals helps identify many of the species throwing blips on last night’s radar. Today’s new arrivals included: Blue-winged Teal, Double-crested Cormorant, Pectoral Sandpiper ,Wilson’s Snipe, Bonaparte’s Gull, Eurasian Collared-Dove, Yellow-bellied Sapsucker,Winter Wren, American Pipit
Yellow-rumped Warbler,Savannah Sparrow, Swamp Sparrow , and Eastern Towhee.
Waterfowl numbers were generally low, but the 14 species diversity was good. A late push of 600+ gulls seems to indicate that Ring-billed Gulls are still migrating. However, many local birds have returned, so this can be hard to ascertain.
Flickers were the surprise this morning, as they started their longshore appearance with a bang. Usual flicker flights don’t occur until April, with exception of a March 20-28 flight in 2012 during the hot spring and summer. So it shouldn’t have been too much of a surprise to see them ready to go, given the warm February we received last month. 201 Flickers flew past through the morning hours.
Other notables for the day included 362 Tree Swallows, 850 American Robins, and eight species of sparrow. A Fox Sparrow was singing near the tower site, but not as impressive as the 80 reported today at the Hammond Bird Sanctuary by Michael Topp. This count likely represents a new state record count.
Today’s complete list of all 70 species is here. We’re at 99 species for the season now. What will number 100 be!?
The upcoming storm systems will make counting hard the next few days. Some south winds will reappear for Sunday, but rain is still inthe forecast. The week will hold fickle weather with shifting winds nearly daily, before the long range shows some strong south winds Thursday into Friday, with tight gradients, which would mean gusty conditions again before shifting back to the north for next weekend and start of April. Looks like the same month that came in like a lion intends to go out the same way!
