Moist Advection!

Thursday, April 9 brought a brief return to longshore counting in the dunes.  The previous couple of days have been a mix bag of rain, north winds, and generally poor migration conditions.  Even today was in the air, as east winds were predicted to dominate the area.  However, dawn found the dunes smack dab in the middle of two storm fronts moving through the lower Great Lakes.  Conditions were warm, moist, and full of birds migrating between the storms.  The southerly winds were bringing warm and wet air from the Gulf, but also birds that have been staging in southern Indiana and points south.

By noon, storms rolled in and shut down migration, but not before 10,000+ birds were logged, comprising 70 species.  New birds for the year included Pied-billed Grebe, Wilson’s Snipe (in the prairie), Northern Rough-winged Swallow, Hermit Thursh, Savannah Sparrow, and Swamp Sparrow.  Clearly new birds were riding the moist advection overnight.

Blackbirds and grackles put on a good early morning movement. Particularly grackles.  5,000+ grackles, doubled the number of red-wings moving through.  Also notable in numbers were 21 Yellow-bellied Sapsuckers.  Not record count, but still pretty good.

Without the sunshine, the raptors didn’t put on a very big flight, but the fast flying raptors took advantage of the south winds.  4 Merlins doubled the season total thus far.  Kestrels, Peregrine Falcon, and Sharp-shinned Hawks rounded out the majority of raptors today.

Exciting news to share is the first Osprey on the Dunes State Park Osprey tower.  If you remember, the towers were put up last year and reported in our blog in 2014.  Well now, a year later, Becky Muraro was able to capture the following photo from atop the Kemil Rd tower. It hasn’t been seen since, but it’s obvious that the first Osprey has already taken notice to the beautiful nesting site!  If you build it….
