The day began on a high note. As usual, my husband Darrin O'Brien and I drove friend and participant Cathy Carroll to her starting point, so she can walk along the west side Rouge River back to her car on campus. Due to the fact I have just turned old enough to join the AARP (or, perhaps, a lack of coffee), we drove her to the wrong spot! My dunder-headedness turned out to be serendipitous, as I spotted an adult Bald Eagle perched in a tree along the Lower Rouge River just west of Evergreen Road. As we pulled over to admire it, I got a call from my co-worker Rick Simek, who was covering the south end of campus. He excitedly told me he had just flushed an adult Bald Eagle! Later, Greg Norwood, covering the north end of campus, also saw the eagle; Cathy saw it again later, too. While eagles are getting more and more common in the county and the city, this is only the third time we have recorded this species on the count.
Darrin and I traditionally cover the Ford "sunflower" fields which can vary in productivity from year to year depending on which ones are planted, and with what. Usually, the most productive field is the original field at Hubbard and Southfield. However, the last few years it has been planted in hay. (Curiously, given the very high prices and demand for hay this year due to the drought, the hay was still being stored on-site in the field.) Sometimes a cover crop is used for winter, but this year it (and the one across the street) was left fallow, save for a narrow fringe of sunflowers along the edges, long since picked over. There wasn't much at this field, nor any of the others except the one adjacent to Ford World Headquarters.

The horse paddock at Greenfield Village once again yielded Horned Lakes (five). Darrin spotted one first, and it prompted this exchange:
Darrin: I have one. It's on the pile of poop to the left of the side door.
Julie: Got it. And here's another...now three...four...five.
Darrin: What?! Are you on the same poop that I am?

paddock is right after they are fed, and hay piles are strewn about.
The summer drought played a role in our bird sightings. The soft mast crop (berries and other fruit) was the poorest I can remember. Our 66 American Robins was the lowest number we've counted since 1999; the average over the last decade is over 250.
The drought may also be partially to blame for the widespread tree crop failure (seeds, cones, and other hard mast) this year. Earlier in the season we experienced movement of just about every "winter finch" through the area in search of food. Many kept going, but at least a few hung around. Our total of 23 Pine Siskins on campus was part of a flock that has been either visiting the feeders or feeding on European Alder cones. This was only the fourth count they have been recorded, and this is a record number.
Surely the highlight of the day was also one of the wandering winter finches: ten White-winged Crossbills on a spruce tree in Detroit River CBC compiler Jim Fowler's back yard. This is a new species for the count, bringing the Dearborn cumulative species total to 86.
We ended the day with 47 species, which is one above average. We added a count week species the next day (Brown-headed Cowbird) at the campus bird feeders.
*Although RRBO has been coordinating the Dearborn portion of the count since 1995, we've only had uniform coverage of the city since 1997.
