Hi folks, this is more a cautionary heads-up than anything else but with all the Bohemian Waxwing reports of 100, 250, 300 birds etc. and plenty more to be seen yet this winter and spring I'm curious as to whether folks are making actual counts, systematic estimates, or gross estimates of overall flock size? In my experience, birders (myself included) vastly underestimate flock size in this species, often upwards of 40-70%, i.e. a flock estimated at 100 often has 140-170+ birds. Don't ask me why but without alot of experience it's very difficult to correctly gauge numbers of this species without actually counting, or at least more systematically estimating (e.g. 5, 10, 20 birds at a time). So I challenge you the next time you're up north to first estimate flock size as we often do and then make an actual count. My money says there will be far more birds than you thought!
