Did you know there are two
different species of hummingbirds in the Vancouver area? The rufous hummingbird
is a tiny orange-red hummer that visits B.C. each summer and winters in Mexico,
while the slightly larger maroon-and-green Anna’s hummingbird is here all year.
Anna's hummingbirds have increased
their numbers in B.C. dramatically in the past two decades in response to the
warmer climate and availability of year-round food. It is on the front cover of
the new Birder’s Guide to Vancouver, and it is one of many bird species
spreading across the province, as demonstrated by the newly released British
Columbia Breeding Bird Atlas. The atlas was published online this
month, coinciding with Vancouver
Bird Week, International
Migratory Bird Day, and the 100th anniversary of the 1916
Migratory Bird Treaty Act.
The B.C. Breeding Bird Atlas is
based on an unprecedented five-year field survey carried out by an army of
enthusiastic volunteers and coordinated by the nonprofit group Bird Studies
Canada (BSC). Its
completion required more than 56,000 hours of fieldwork that collected more
than 630,000 records. This massive collaborative effort involved impressive
numbers of people: 1,300 field volunteers, 40 writers and editors, 45 regional
coordinators, 40 photographers, and 150 partners and special contributors.
