Figure 2-6. Typical display of eBirdRad avian radar system, NAS Patuxent River, 17 April
2007, 21:45 EDT. North is up; radar range setting is 3 nmi (5.5 km), range rings are 0.3
nmi (556 m) apart. Red trails are target tracks; white label at the head of a track is the
target’s speed, in knots. ....................................................................................................................... 19

Figure 4-2. MCAS Cherry Point, North Carolina, showing the location of the eBirdRad radar
(RT-1) and the visual team (VT) observation sites used in the spring 2007 (’07) and fall
2008 (’08) studies. ............................................................................................................................... 48
Figure 4-3. Site C at the Outlying Field (OLF) location in Washington County, North Carolina.
The eBirdRad radar at the “OLF Site C (’06)” site was used to monitor bird activity near the
location of a proposed runway, while the “Wildlife Refuge (’06)” eBirdRad radar was
monitoring bird activity in the adjacent Pocosin Lakes National Wildlife Refuge. Data
collected in February 2006 from these two radars were used by the IVAR project in its data
fusion studies. ...................................................................................................................................... 49

and the visual team (VT) observation sites used in the spring 2007 (’07) and fall 2008
studies. VT site labels without a year designator were used in both 2007 & 2008. ........................... 50
