16 July 2018 – Ruby-throated Hummingbird

Casualty #357 on this project was not a magnum, it was more of a micro: this apparent HY male Ruby-throated Hummingbird at the southeast alcove.

15 May 2018 – Magnolia Warbler and a trapped Clay-colored Sparrow

I found a trapped Clay-colored Sparrow today in the southwestern alcove. Upon release in the relative safety of a nearby shrub, the bird flew off another 5m or so to another shrub, where it perched strongly.

Less lucky was the Magnolia Warbler I found in the northwest alcove. This bird, a female with fat = 3, was just the second of this species documented on this project.

14 May 2018 – Baltimore Oriole

I found just the second-ever Baltimore Oriole on the project today, at the main north entrance. This was a SY female (fat = 2, 33.5 g) showing extreme feather wear and asymmetrical flight feather molt. See especially the difference in the 2nd tertiary (S8, if you prefer) between the left and right wings.

Note – a dull-plumaged female Baltimore Oriole can be difficult to distinguish from Bullock’s Oriole. This bird was easy to discern as Baltimore owing to brightest yellow in the center of the upper breast/throat (instead of higher on the cheek/malar), more brownish rather than grayish upperparts, and dark centers to brownish feather of the scapulars.

13 May 2018 – two Swainson’s Thrushes

The Indigo Bunting has been removed – May 12 – but the Painted Bunting and Yellow Warbler remain.

The odd thing today was that I found a dead Swainson’s Thrush along the northern wall. This might be the first casualty on this side of the building since monitoring began in August 2009. I then found a second – and alive! – Swainson’s Thrush in the southwestern alcove. The bird was feisty in the hand and perched strongly when I placed it in a nearby shrub.

10 May 2018 – Painted Bunting

The hint of yellow at the gape suggests that this might be a second year (SY) bird, but it is seriously bright green. I’ll tentatively call it an SY-U because it looks to be that the brightness of the green is not a reliable character for discriminating between adult females and young males.

8 May 2018 – Indigo Bunting

Corey Riding reported that the Lincoln’s Sparrow has been removed.

Corey also found this apparent AHY-F Indigo Bunting at the main north entrance. (I took these photos on May 9.)

6 May 2018 – Ruby-throated Hummingbird

Today, Corey Riding found this AHY-M Ruby-throated Hummingbird in the southeastern alcove.
