75 Species in 4 hours

Wow, I didn't realize it until I entered my data into eBird, but this evening after the storm passed I broke my record for number of bird species seen in one outing. Between 4:30 PM and 8:20 PM today I found 75 species of birds on Lake Creek Trail! I'm just too tired to write up all the details, but a few highlights are:

• 10 species of warbler, including a Blue-winged Warbler, a Magnolia Warbler, and at least 16 Common Yellowthroats
• 6 Rose-breasted Grosbeaks
• Indigo Buntings and Painted Buntings
• the first Common Nighthawks I've seen this year

I've thought about this before and tonight makes me think about it again. Under the right conditions at the right time of year, is a Century Day possible in the neighborhood?
