SITE INFORMATION SITE LOCATION and ACCESS
The Rose Tree Park HawkWatch is located in Rose Tree Park, onRoute252justnorthoftheRoute1MediaBy-pass,DelawareCounty,PennsylvaniaatN39o 56.43’ - W 75o23.52’Elevation-315feet.
The spring hawk watch site within the park is located at the northern edge of the east parking lot. The fall hawk watch site is located north of the gazebo between the two parking lots (See Appendix 1)..
DATES, TIMES, and WEATHER
Rose Tree Park HawkWatch operates a fully-staffed spring and fall hawk watch.
SpringThe spring migration season is shorter than the fall and much less predictable. Hawks are less gregarious in the spring as they make their way toward their breeding grounds and tendtoflyoveramuchbroaderareathaninthefall.Springcounts are generally much lower than in the fall. The RTPHW officialspringseasonisfromMarch15throughtheendofApril.Theaveragetotalcountforthespringisabout2,200birds, although in the spring of 2002 RTPHW recorded morethan4,400hawksincludingover2,000Broad-wingedHawks.Mid-Aprilisthemostactivecountperiodforthespring.Whentherearefavorableflightdaysoutsidethecorespring dates it is likely someone will be at the hawk watch site recording hawk counts.
FallThe fall migration is more predictable. Like clockwork, one cansetacalendarforwhatspecieswillbeflyingwhen,andwill generally know the peak count periods of each species.

The hawk watch site is staffed during the core time using the current local time frame (DST, EST). Data collection is always compiled using Standard Time.
WeatherRTPHW will be staffed daily during the core dates and times under most weather conditions. The hawk watch will be closed or shut down during periods of steady precipitation.
It is expected that the hawk watch be staffed during the following weather conditions.Any clear days, despite potential uncomfortable

COUNTING HAWKS
Inmosteverycasemigratinghawksarecountedindividuallyorin small groups at RTPHW. There are few exceptions since the volumeofbirdspassingthroughourareaatanygiventimeisusually quite manageable.
Hawksthataremovingwithpurposeandintentinthepropermigratory direction are considered to be migrant hawks and should be recorded as such.
Therearehoweverseveralsituationsandhawkspeciesthatrequire special attention. BROAD-WINGED HAWKS
Broad-winged Hawks (BWHA) migrate through RTPHW in mid-April in the spring and mid-September in the fall. The BWHAisalong-rangeflockingmigranthawkand,iftheweatherconditionsarefavorable,theymaycomethroughingreat numbers at a time. When BWHA does come through in large numbers special count criteria should be followed: The most accurate count of Broad-winged Hawks
isobtainedbycountingindividualbirdswhentheyare streaming out of a kettle. Locate the lead bird of thestreamthenindividuallycountthebirdsbacktothe end of the stream. Either let them pass in front of your stationary optics or pan to the back of the streamlookingaboveandbelowthestreamtopickupadditionalbirdsthatmaybestreamingaboveorbelowthe main stream.
During periods of strong winds kettles and streams of BWHAmayoftendriftwiththeprevailingwinds.Ifdistant kettles are located and appear to be drifting away from the hawk watch site, count as many of the
7
birds in the kettle that you can see. If the kettle drifts out of sight the number of birds counted should be recorded. DO NOT estimate the number of birds that might be in a kettle. Record only the birds actually seen and counted.
OnBIGDAYSwhentherearequalifiedobserversavailableusetheobserversasaresource.•Splitobserversupandassignskyquadrants–at
leastonequalifiedobservertoeachgroup.– The counter should coordinate the count
groups – compiling the totals from the groups andsupervisingtheskyassignmentstoinsuredouble counts aren’t being made.
– Observersshouldberemindedtolookforotherspecieswithinthekettlesandtoprovideanaccurate count on those as well.
•Ifqualifiedobserversareconcentratingonthesamekettle, scan the sky and look for other incoming birds or kettles.
Should the counter be alone when the BWHA are coming through, which is highly unlikely at RTPHW, the counter should use a grouping method to ascertain thenumberofbirdsinindividualkettles.•First examine the kettle for other hawk species
then take a section of the kettle and quickly count the number of birds in that particular section, determine the number of similar sections in the kettle then multiply the counted section by the total number of similar sections in the kettle. Thiswillprovideanaccurateestimateofthetotalnumber of birds for that kettle.
•Movetootherkettlespresentandrepeattheprocedure. Check the entire sky often for other incoming or distant kettles.
VULTURES
Vultures are counted at RTPHW using the same criteria that we use for other migrating hawks – moving with purpose and intent in the proper migratory direction.

ACCIPITERS – Sharp-shinned and Cooper’s HawksIt should be noted that many Sharp-shinned and Cooper’s hawksmigrateandforagesimultaneously.Weoftenhavetheseaccipitersflyingjustoverthetreetopsastheymigratethrough. This can occur at any time of the day but it is most likelyobservedinthemorningandlateafternoon.
Ifthisbehaviorisnotedandthebirdisheadingintherightdirection, with purpose, it should be considered a migrant hawk and be counted.
HAWKS GOING TO ROOSTOften late in the afternoon hawks will start dropping down tolookforovernightroostsites.Whenthisoccurstheyoftenflyinalldirectionslookingforafavorableroostsite-thisisespecially true of BWHA.
Hawks that drop down to roost before passing the hawk watch site should not be counted but should be noted in order to alert the next day’s Site Coordinator.

Hawks that pass beyond the hawk watch site in search of a roost should be counted as migrant hawks.
COUNTING OTHER NON-HAWK MIGRANTSOther migrant passerines should also be counted and noted. The following species should also be counted and recorded on theOtherMigrantsform.

SCANNING TECHNIQUES Scanning the skies in an organized manner is the principal method for locating migrating hawks and discerning them from local hawk populations and other birds in general.

Binocularscansshouldbemadebothinahorizontalandverticaldirection. Scans should be concentrated towards the north to east quadrant with the greatest concentration towards the northeast during the fall season, and in the spring the scans should be from the west to south quadrant with the greatest concentration towards the southwest.
A scope should not be used for scanning because the optics of the scope allow only a minute window of the sky. Scopes should be used for identifying an already located bird or for educational purposes.
DATA COLLECTION and RECORDINGThe primary objective at RTPHW is to identify each passing hawk to species.Thenumbersobservedarethenrecordedonthehourlycountsheets.
The secondary objective is to determine additional information regarding the migrating hawks as outlined below.
It is important that data collection be consistent and standardized in ordertoobtainviablestatisticalanalysisforscientificpurposes.

RTPHW uses the weather data that is collected at the Philadelphia International Airport (PHL) with the exception ofthecloudcoverwhichisrecordedatRTPHW.

The PHL weather recording site is located 8 miles ESE of RTPHW and records daily and hourly weather conditions similar to RTPHW.

Comparison of weather data between RTPHW and PHL is conducted at the beginning of each fall season todeterminethevalidityofusingthePHLdata.Overthe last four years the data remains quite similar on a dailybasiswiththeexceptionofcloudcoverwhichisrecorded hourly at the RTPHW site.
