Out of curiosity I have been checking in on the eBird data and the results are conclusive and impressive. Check out the maps and frequency charts below.
|2011 August through December Evening Grosbeak sightings.|
|2012 August through Nov 15th - Evening Grosbeak sightings. Significant deeper entry into the Southwest, Midwest, Northeast, East Coast, even starting to enter into Southern states.|
|2011 Frequency of checklists reporting Evening Grosbeaks - Pay attention to October and November when you compare it to the 2012 Frequency Graph below...|
|While May-June sightings were slightly less frequent in 2012, take a look at September through today. Awesome!|
