There's an upcoming birding event in New Jersey modestly named by its promoters as "The World Series of Birding." It is a Big Day big deal.
The object is to see as many bird species as possible in a designated period within a particular geographic area. Big Days — 24-hour efforts — are very common.
The competitive World Series event — on May 12 this year — covers the state of New Jersey. It involves serious planning and secret routes. The winning total last year was 212 species.
You, though, could have a Big Day in your yard that lasts, say, 60 minutes. That would be a Big Hour. Less planning would be needed.
You could do your listing in your favorite park, your county, the state, North America, or the world for a day or month or year.
Among recent well publicized Big Year efforts, an Oregon man, Noah Strycker, wrote a book about his 2015 worldwide quest, in which he saw 6,042 species of birds.
The next year a Dutch birder pushed that number to 6,833. Fame is fleeting. The Dutchman saw about 70 percent of the world's known bird species.
Dead birds don't count. Identification, by eye or ear, must be certain. There are no referees. Birding is an honor sport.
