Hundreds of birders were in the field throughout Arizona on May 9 for the
Global Big Day spring migration count. We tallied 304 species, which was a
good showing.
One new species was added to the 23-year cumulative state list for the
migration count: TRICOLORED HERON, amazingly two of them, one each in Gila
and Maricopa counties. For only the second year we tallied American
Golden-plover (Coconino), Black-bellied Plover (Coconino, Pinal), and
Laughing Gull (Pinal). Forty species from 10 counties were reported from
only one county. No county reported their highest number of species in 23
years, but Pima County scored its second highest (208). The totals by
county were: Cochise (218), Pima (208), Coconino (185), Maricopa (184),
Pinal (179), Santa Cruz (171), Yavapai (170), Gila (155), Graham (154),
Navajo (122), Apache (116), Mohave (85), Greenlee (58), Yuma (58), and La
Paz (18).
Only five species were reported from all 15 counties, which was mainly due
to the small totals from a couple of counties. As in most previous years,
Arizona had the third highest number of species in the United States after
Texas (399) and California (376). New Mexico (289) was fourth.
Figures tallied for four wood-warblers that migrate through but are not
known to nest in Arizona were the highest in five years for Townsend’s
Warbler (122), but were lower for Wilson’s Warbler (262), Nashville Warbler
(5), and Hermit Warbler (7). Both Rufous and Calliope hummingbirds were
reported in seven counties compared to their previous high of four counties
each. Forty-four Calliope Hummingbirds and 20 Rufous Hummingbirds were
reported.
The final tallies will be posted on the AZFO website where they will appear
with the results of previous years.
