I'm bugged about the bird surveyors in Louisiana that shot the first Crowned Slaty-Flycatcher ever discovered in North America instead of alerting the U.S. birding community.
(PS I'm in personal communication with folks from LSU and those involved in collecting this bird. We clearly disagree about the merits of collecting vagrants but we aren't going to change each other's minds through online debate. I'm not accepting further comments on this post since I'd prefer to disagree without being disagreeable and would rather not risk flaming the fires online where passionate words often miss their mark. These are discussions more suited to personal communication, preferably while out in the field enjoying the birds we all love.)
