Flowering Pear Trees were put on the “Do not Sell”, Invasive Species List for the Ohio Department of Agriculture last January of 2023. The problem is the fruit!

Strafing Starlings and Callery Pears boggs.47@osu.edu Tue, 11/14/2023 - 18:10
During a recent Sunday drive, my wife and I came across a dramatic display of the fruitful connection between European Starlings (Sturnus vulgaris, family Sturnidae) and Callery Pears (Pyrus calleryana, family Rosaceae). The lead image needs no label.

Callery Pear: the Jekyll and Hyde Tree

Last year, I vowed not to take any more pictures of blooming Callery pear (Pyrus calleryana). I have hundreds of pictures including some that I've labeled "Field of Pears."

Fireblight This Time

Fireblight on Callery pear is highlighted against the blue sky in Columbus’s German Village this past Thursday in the lead photo of this byglalert, with a different look in the second photo taken with a different sun angle, important to remember when seeing images and thinking “it doesn’t look quite like what I saw”. Fireblight symptoms of “shepherd’s crook” shoots and discolored leaves are common to see now, following infections which occurred weeks, even months earlier in cool, warm weather during bloom.
