May be of interest to some NatureNS birders, see below.
Take the elevator to the 5th floor in the Biology Dept, LSC; 5th floor Loun=
ge is at the end of the corridor. (This is in the Life Sciences Ctr, Dalhou=
sie Univ: the LSC megastructure building sits off Oxford St, near the inter=
section with South St).
Seating is likely to be limited if the talk is popular, sometimes you have =
to stand.  Parking will also be difficult at 3:30PM =97 try Oxford St (2 ho=
urs) or a parking meter, e.g. in new Steele Ocean Building lot.

Hi all,  Please join us for this week=92s Biology Department Seminar, from =
3:30-4:40 in the 5thFloor Biology Lounge.  We=92ll hear from Dr. Joe Nocera=
, Assistant Professor, Faculty of Forestry and Environmental Management at =
the University of New Brunswick.
TITLE:  =93Are declining aerial insectivore populations limited by food or =
habitat?=94
ABSTRACT:  Aerial insectivores, a guild including bird species that forage =
on flying insects, have experienced marked population declines in North Ame=
rica; however, the reasons for the declines are not well understood. Explan=
ations have centered on species-specific habitat loss or the fact that all =
aerial insectivores share a common diet.  Management of aerial insectivore =
populations seems to have been exclusively focused on habitat issues, despi=
te the commonality among them all in terms of diet.  I argue that this may =
be a function of tractability: managing habitat is a much more tractable ex=
ercise than trying to manage insect prey populations.  Through intensive st=
udies of Chimney Swifts (Chaetura pelagica) and Eastern Whip-poor-will (Ant=
rostomus vociferus) I have investigated several hypotheses to explain the d=
ecline aerial insectivore populations. In addition, I have taken broader vi=
ews to investigate issues that may affect the entire guild.  I will present=
 evidence that illustrates that for some species, such as Chimney Swifts, h=
abitat is not a limiting factor but prey is.  For other species, like the E=
astern Whip-poor-will, the causes behind population decline are more comple=
x and involve both habitat changes and prey populations.  I will conclude w=
ith a broad overview that assesses population limitations on the wintering =
grounds as well.
For meetings with Dr. Nocera, please contact Tara Imlay <tara.imlay@gmail.c=
