I try to get in at least one day of birding at Mt. Auburn Cemetery each year during peak spring migration.



I made my trip there right on the cusp of peak migration- April 30th. I usually try to get there sometime in late April- early May to see the greatest variety of wood warblers, plus other colorful migrating birds.
The day I was there I got to see some of the usual warblers, and even a lifer for me- the chestnut-sided warbler. Maybe I had technically seen this bird before on a group trip where it blended in with the rest of the birds we saw, but on this day it definitely stood out to me as the most exciting warbler of the day.
Here are some pictures of the Chestnut-sided Warbler preening:


Other (non-photographed) highlights from the day included:
Northern Parula
Yellow-rumped Warbler
Black and White Warbler
Black-throated Green Warbler
Baltimore Oriole
Chipping Sparrow

Here's a red-tailed hawk we saw at the end of the day as we were walking back to the car. That's usually where I see them at Mount Auburn Cemetery- in the areas surrounding the main entrance (in the circular parking area, near the entrance to Indian Ridge, near the main office, etc.).

I even have a MYSTERY BIRD to ask for help with. I've tried identifying it on my own, and think it could possibly be a juvenile or female indigo bunting, but I didn't see any male indigo buntings that day, so I can't say for sure how likely it would be to see that bird at Mt. Auburn Cemetery on that date.
Mystery Bird:
The most distinguishable characteristics about this mystery bird are the grosbeak (fat thick beak), the subtle wing bars, and a faint eye line. Click on the images to zoom in more. Thanks in advance for your identifying help!

When I first saw the bird a female Brown-headed Cowbird popped to mind.
Also (and again it is hard to tell) but the bill appears be all black.
A quick search found me this link which you might find interesting - although not sure it resolves the mystery for you! :)

Congrats on the lifer - Chestnut-sideds are really cool, sweet warblers!
I have to agree with everyone- looks like a female brown-headed cowbird to me. Now I know!
