The White Clay Creek State Park is the 4th highest ranked top birding spot in New Castle County and 49th largest Delaware area bird list by Cornell University’s eBird data base. This list is growing as more hours are spent birding the area. The purpose of this bird survey is to evaluate the avifauna potential in a systematic two-year study and add to the knowledge of the park. The survey takes 3-4 hours and covers about 3 miles. The park was originally surveyed in 1976-1977 with weekly surveys over 24 months. That data was published in the Delmarva Ornithologist. \n\n\n\nMagnolia Warbler by Chase Wilkinson\n\n\n\nPlan:Date: January 2\, 2026 – December 31\, 2027Frequency: Weekly\, alternate Thursday/SaturdayCoverage: North and South sections split by Hopkins and Pleasant Hill Roads.Data Entry: Checklists will be recorded by eBird along with weather\, observers and effort.Volunteer Hours: recorded on separate volunteer sheet.Goals:Count the total number of birds in the park over a 24-hour period weekly for 2 years.Document status and population of bird species.Locate critical areas for unusual species.Increase usage for birding activitiesMonitor volunteer hours (between 350-750 hrs./yr) \n\n\n\nCensus Dates: The dates for the weekly bird census may be modified based on the consensus of thegroup. Changes to the schedule can occur in response to weather conditions or other unforeseen factorsthat may affect census activities. \n\n\n\nCensus dates for 2026 continue as follows: \n\n\n\nThursday\, September 10Saturday\, November 14Saturday\, September 19Thursday\, November 19Thursday\, September 24Saturday\, November 28Saturday\, October 3Thursday\, December 3Thursday\, October 8Saturday\, December 12Saturday\, October 17Thursday\, December 17Thursday\, October 22Saturday\, December 26Saturday\, October 31Thursday\, December 31Thursday\, November 5 \n\n\n\n\n\n\n\nMeet at the Chambers Rock Road parking area.

Moore DESCRIPTION:Summary: This talk will be held in person only at the Delaware Museum of Nature and Science and will be held in the bird collection. There will be an opportunity to examine actual museum specimens of Dowitchers to see first hand the issues described in the talk. \n\n\n\nThe two Dowitcher species present one of the most difficult identification challenges among North American birds. Both species occur in Delaware in good numbers. Recent work has revealed several new identification criteria that will be covered in this talk as will some widely used field marks that are not as reliable as previously thought. The goal is to increase your confidence in identifying these two species as well as learning when they are best left as Dowitcher sp. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nDr. Michael Moore is a past president of DOS and a retired Biology Professor. He earned his doctorate at the University of Washington in Seattle and was on the Faculty at Arizona State University for almost 30 years before moving to the University of Delaware in 2011 and then retiring in 2020. He has published over 100 scientific papers on reptiles\, birds and dragonflies. He has been a passionate birder for 50 years and enjoys chasing rarities and working through identification challenges. He is currently the chair of the Publications Committee for DOS. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nThe meeting is held IN PERSON ONLY at Delaware Museum of Nature and Science. The in person meeting is open to everyone and admission is free. The presentation will involve looking at actual museum specimens of the birds discussed\, so cannot be live streamed. Please come out and enjoy this unique hands on experience.

This small section of Middle Run Natural Area provides the hedgerows and early-successional habitat that migrants like warblers often use during fall migration. The height and arrangement of vegetation here also provide ample opportunities for photography. Grassy and scrubby fields provide great habitat for migrating and overwintering sparrows\, which may start to show up by late September.  \n\n\n\nWill Krohn will lead a walk for approximately 1.5 hours in this park\, walking on grassy trails over gently to mildly sloping terrain. We will travel about a mile\, slowly walking around to look for mixed-species flocks\, botanizing along the way if the birds are quiet. We will meet at 8:00 AM at the grassy field where Polly Drummond Hill Road meets Smith Mill Road. You can park in this field\, but remember to drive slowly when entering the field from the road\, as there is a big bump here that low-clearance cars should be careful of. There is no bathroom on-site. \n\n\n\n Contact Will Krohn (wkrohn@udel.edu) with any questions.
