55 Rufous Hummingbirds Found in 2013 Count

Eastside Audubon’s second annual Rufous Hummingbird Count found 55 individual birds, higher than the 2012 count with its 47 RUHUs.

The 2013 count period ran from Friday, May 31, to Monday, June 3. Seventeen people sent in reports to EAS, and the final tally included six additional reports posted to eBird during the count period.

Rufous Hummingbird by Larry EnglesRufous Hummingbirds were seen in 23 locations. Redmond led all cities with 21 RUHUs reported. The Woodinville and Lake Joy areas followed with 9 and 8 respectively.

Good Reporting

Of the total, 26 were male, 20 were female, and 9 were unidentified as to sex. Of those whose sex wasn't identified, 8 were reported in eBird, where observers do not specify the gender of birds. The ability of reporters to discern male from female RUHUs showed improvement: In 2012, 12 RUHUs were unidentified as to sex, with only 5 of those in eBird reports.

It is difficult to determine any trends in the data after these first two years. The increase from 47 to 55 RUHUs is not statistically significant because the samples are so small. However, we can say that there is consistency in the number of likely breeding RUHUs in the EAS service area.

Thanks to all of the EAS members who reported on the RUHUs seen at their feeders or local parks. We are also grateful to those who posted their sightings in the eBird database, a service of the Cornell Lab of Ornithology.
