Happy Easter. No longshore flight officially is taking place today due to the holiday. However, Saturday, April 15th brought a very warm day to the dunes and is worth reporting. Overnight spotty storms and south winds created a warm wind at dawn that increased through the day. Like a good Saturday does, a contingent of bird enthusiasts joined our counter at the tower for an excellent morning of longshore flight. By noon, temperatures were in the low 80s. The group of birders logged 6,942 birds from 74 species. Here are the highlights:
Little movement occurred over the lake, as the majority of waterfowl appear to have moved through. Loons however, are still present. 3 Common Loons were seen on the water, but more significant was a good flock of 18 Red-throated Loons that took off from the water as a fishing charter boat went by past the park.
New for the season were House Wren, Palm Warbler, Orange-crowned Warbler, and White-throated Sparrow all right on time for the year! The early wave of neo-tropical migrants was evident today, as the first rounds of typical early season warblers passed in full force Saturday. 37 Blue-gray Gnatcatchers was a significant early season movement of the the little buzzers. The butter butts, aka Yellow-rumped Warblers, made a significant flight in front of the counters, often moving at eye level throught the nearby dune oak canopy, and landing briefly before pushing on towards Chicago and eventually Canada. 348 butter butts went by. It wasn’t a state top 10 count, but still quite good. In addition to the previously mentioned Palm Warbler, Pine Warblers moved through in excellent numbers too. The day’s 23 Pine Warblers is the highest Pine Warbler total in the five years of official longshore surveys, and likely the state’s second highest single day count.
Likely due to the stronger wind speeds, the thermal development suffered and the day’s hawkflight failed to really materialize. Only 49 raptors went by the tower. Osprey and 5 Broad-winged Hawks were the highlights for the birds of prey.
Saturday’s full count can be found on ebird here. The weather outlook looks good for some upcoming counts, so expect the birds to keep coming! The season total species count so far is 137 species.
