Hi Harry et al
Thanks for your email re. shorebirds in the mountains. Yes, I agree that the e-bird filters are somewhat baffling. We even tested the filter by putting in over 20 Buff-breasts - again, no rarity box popped up! As for details entered. Never easy to do when you are entering data using the cell phone app - all done now!!
Anyway, filters aside - that is for the e-bird regional editors to monitor and adjust.
As for large plovers, both species have been present this past week. I have personally seen the Black-bellied Plovers, but the Am Goldens have eluded me on 2 visits. Multiple observers have seen the Goldens, so they are certainly around. There are photos on e-bird proving these sightings. Both species are regularly seen during spring and fall migration - weather depending of course.
There are many tracks to explore and it could take you all day to walk the road beds to find any of the flooded areas. These usually occur where the sod has been harvested, but due to work gong on most days, the birds constantly move from field to field. In other words, there are lots of places where birds can be, and consequently, lots of birds. Plus a lot of the area is private property- hence, no access.
As for my reports today, I stood in 1 spot on Jeffress Road and never walked into any of the fields. The Black-bellied Plovers were at least 1.5 miles away from my position the previous day, so I never bothered to go that far. All of the shorebirds I reported today were from this one location! And yes, there were NO peeps present except the Baird's......the previous visit we had 1 Least......that's all!. As for Buff-breasted Sandpipers, yes, we had 7 today and 9 yesterday.
To conclude, yes e-bird filters are a little odd for shorebirds in the mountains. The other day we had over 100 Killdeer (e-bird flagged!) and over 80 Eastern Kingbird migrating over (e-bird not flagged!) How often do we see 80 Kingbirds in one day? Never!
Anyway, we do need to add as much data as we can with shorebirds in the mountains. Photos are useful, but plumage descriptions are also important. E-bird is not perfect, but it's an awesome tool that can add so much to our knowledge of birds here in the mountains and throughout North Carolina.
