2017 CENSUS SUMMARY The 31st annual Philadelphia Mid-Winter Bird Census was held on Saturday January 7, 2017. Ninety-two participants organized in 35 parties took part in the 2017 census recording 98 species and 20,400 individuals. Unfortunately, the 2017 census was impacted by a major snowstorm on census day. The original weather forecast for the 7th called for overcast skies and possible flurries. But this forecast gradually changed each day leading up to the census and the length and severity of the storm that actually occurred on the 7th was much greater than what had even been predicted the day before. The storm, which lasted for most of the day, impacted the census in two significant ways. First, it made the physical task of looking for birds much more difficult. While conditions before sunrise were very cold but pleasant, snow began to fall during the early morning hours and it continued through the late afternoon by which time three inches of snow had accumulated. During this time the falling snow waxed between light and heavy squalls and visibility was sometimes reduced to less than a quarter mile. A moderate breeze often caused snow to blow sideways coating binocular and telescope lenses - which were also subject to fogging as they went from warm cars into the very cold temperatures outdoors. And the snow, which began sticking to roadways very quickly, made driving more difficult by causing roads to become slippery, obscuring lane lines, freezing on windshields, and slowing travel times. Because of these challenges many parties were unable to cover their areas thoroughly, and some areas could not be covered at all. Altogether the storm caused the amount of birding done this year (171 party hours) to fall about 20% below the amount done last year (210 party hours). The storm also had a direct impact on birds. The snow caused many birds to become less active, especially some species that are typically observed flying like vultures, hawks and crows. And it caused reclusive species that often remain in dense cover like Gray Catbirds to become even more difficult to find or, in the case of Brown Thrasher, impossible to find. Even common species like House Sparrows, Rock Pigeons, and European Starlings were recorded in unusually low numbers this year because of the snow. Overall, the 98 species and 20,400 individuals recorded were the lowest totals for species and individuals since 2011 when 90 species and 19,351 individuals were recorded. 2011 was also the only other year in which the census was held during an active snowstorm. Despite the storm’s overall effect on this year’s results, the 98 species recorded actually exceeded the number of species recorded on any of Pennsylvania’s 74 Christmas Bird Counts (CBCs) this winter except for the Harrisburg, CBC which recorded 100 species on December 17. For this impressive result I would like to thank all of this year’s participants for going out and persevering through what were probably the most challenging weather conditions ever experienced during the census’ 31 year history.

This year only one species was recorded that was new to the census. A Black-headed Gull (first cycle individual) that had first been reported at John Heinz National Wildlife Refuge (JHNWR) on December 25 by Victoria Sindlinger and subsequently observed there on a daily basis, was observed at the refuge for a brief period during the morning. By late morning the impoundment where the bird had been observed had frozen and the bird could not be found for the rest of the day. Much thanks to the McGovern party for finding the gull and for taking some excellent photos of it while it was present. These photos, taken by Kristen Johnson and Holly Merker, are included in the photo gallery at the end of this report. Prior to this winter this rare Eurasian species had only been recorded previously in Philadelphia on January 17th and January 28th 2014 when another first cycle individual was observed at the trash transfer station along South Columbus Blvd. This year’s record of the Black-headed Gull raises the cumulative (1987-2017) species total for the census to 163. In addition to the Black-headed Gull, two other unusual species were recorded this year. During the brief snow free period that occurred right after sunrise a Pine Warbler (apparent adult) was found at the Northeast Water Pollution Control Plant (NEWPCP) by the Windfelder party and also observed by the DiAntoniis and Russell parties. Pine Warblers have been observed many times during the winter in the mid-Atlantic region but this is only the third time that this species has been recorded on the census. It was previously recorded in 1993 and 2004. The other unusual species recorded this year was the Baltimore Oriole observed by Navin Sasikumar and Brittany Stewart at their home in East Falls. The Oriole, which Brittany had first spotted coming to their feeder on January 5, was observed at their feeder on census day by Navin and Brittany around 4 PM after they had patiently waited for the bird to show up for three hours. The oriole, which consumed sunflower seeds while ignoring a nearby orange, was photographed by Navin and these photos have also been included in the photo gallery at the end of this report. This is only the fourth time that the Baltimore Oriole has been recorded on the census, but it is interestingly the third year in a row that the species has been recorded. Prior to the records from 2015-17 the species had only been recorded in 2000. It should be noted that Navin and Brittany also observed the oriole recorded during last year’s census. But that oriole was observed coming to a feeder at a residence in West Philadelphia where they were living at the time. Having a wintering oriole come to your feeder two years in a row at two different widely separate addresses is truly remarkable! A Common Raven was also observed this year at Morris Arboretum by the Best party marking the third time that this species has been recorded on the census. This species was previously recorded in 2014 and 2016. Although this is only the third record of the species for the census the raven is no longer considered a rarity in Philadelphia. Prior to 2009 the raven was unknown in Philadelphia but since that time reports of ravens have become so frequent that the species is now being recorded on an annual basis. And it now appears to have become established as a resident species in all of Pennsylvania’s southeastern counties after having previously been restricted to more mountainous parts of the state.

Several other species were recorded this year that are typically quite scarce in Philadelphia during the winter. George Armistead observed an Iceland Gull (first cycle individual) on the Delaware River at the Philadelphia Naval Business Center during the brief snow free period right after sunrise. This is the tenth time that Iceland Gull has been recorded on the census, but it is also the fifth time that its been recorded in the last 6 years. That Iceland Gulls have not been recorded with regularity on the census until recently may reflect an increase in their occurrence, but it is probably also the result of more targeted searching for them in recent years at key locations they frequent along the Delaware River. At JHNWR two Northern Saw-whet Owls were observed by the McGovern party roosting in dense honeysuckle vines. These birds had originally been found at the refuge in December by David Belford. A photo of one of the birds taken by Kristin Johnson is included in the photo gallery at the end of this report. While Saw-whet Owls probably winter in Philadelphia annually in small but variable numbers they are never easy to find and they probably go unrecorded in many locations where they occur. This year marks the eighth time that the species has been recorded on the census but it is also the fourth time that it has been recorded in the last seven years. Two Orange-crowned Warblers were also recorded this year. One individual was found at the NEWPCP by the Windfelder party, and also observed by the Russell and DiAntoniis parties. Another Orange-crowned Warbler was observed in the large area of fields and woods along the Delaware River at Cumberland Street by Ann Reeves. Other observations of Orange-crowns at Franklin Delano Roosevelt Park (FDRP), JHNWR, and Pennypack on the Delaware (POD) indicate that at least five individuals were present in the city this winter. This is the tenth record of the species on the census and the sixth in a row. The recent increase in the number of Orange-crowned Warblers found wintering each year in Philadelphia at locations like FDRP, JHNWR, the NEWPCP and POD that have been birded regularly for many years suggests that this species has probably increased in abundance as a winter resident in Philadelphia since 2012. Had it not snowed the number recorded this year could have easily exceeed the record high of three (2012, 2013, 2016). The snowstorm caused a number of species to either be recorded in lower than expected numbers or to be missed. Species recorded in lower than expected numbers included common species like the Great Blue Heron – 13 (lowest number since 2010, 2011), Turkey Vulture – 1 (ties lowest number ever), Canada Goose – 2780 (lowest number since 2001), Red-tailed Hawk – 20 (lowest number ever), Rock Pigeon - 288 (lowest number ever), American Crow – 52 (lowest number since 2011), Carolina Chickadee – 251 (lowest number since 2011), Carolina Wren – 138 (lowest number since 2011), European Starling – 2131 (lowest number ever), and House Sparrow – 821 (lowest number since 2011). Species that were probably missed because of the storm include the following that were observed in Philadelphia shortly before and after the census; Northern Pintail (observed January 5 and 8; 5th time missed), Red-breasted Merganser (observed January 5 and 13th; only recorded 7 times), Black Vulture (observed January 6 and 8; 4th miss since 1997 when it was first recorded on the census), Northern Harrier (observed January 6 and 8; 5th time missed), Brown Thrasher (observed December 31 and January 14; only recorded 10 times), Savannah Sparrow (observed January 6 and 8; 8th time missed), and the Brown-headed Cowbird (observed January 4 and 8; 6th time missed). A list of all species recorded in Philadelphia during the two-week period that preceded the census and the two-week period that followed the census is included at the end of this report. Several species were recorded in record high numbers this year including Double-crested Cormorant – 303 (previous high 154 in 2015), Hooded Merganser – 41 (previous high 37 in 2016), and Fox Sparrow – 27 (previous high 24 in 2013). And this year’s totals for several other species were the second highest ever recorded including Gadwall – 121 (all time high 145 in 2009), Yellow-bellied Sapsucker – 29 (all time high 33 in 2015), Pileated Woodpecker – 8 (all time high 9 in 2013, 2014), Palm Warbler – 6 (all time high 10 in 2000), Dark-eyed Junco – 1398 (all time high 1754 in 2004), and Rusty Blackbird – 65 (all time high 77 in 2012). To record such high numbers during a storm that caused the numbers tallied for so many other species to be unusually low suggests that the wintering populations of these species may have been unusually large this year. This year also proved to be a good one for Black-capped Chickadees and Red-breasted Nuthatches which both irrupted into the Mid-Atlantic region in large numbers this winter. Over the last ten years Black-capped Chickadees have only been recorded on the census 4 times, while Red-breasted Nuthatches have only been recorded 6 times. And while this winter did not prove to be a major one for northern finches in the Philadelphia area the four Pine Siskins found by Ann Reeves along the Delaware River at Cumberland St. and the individual Purple Finches found at Southampton Woods (Russell party) and in Mount Airy (Bekker party) followed a long standing trend of non-resident northern finches being recorded on the census mainly every other year.
