Phenology Report: Breakneck bud break, but no woodchucks chucking
GRAND RAPIDS — Leaf and flower buds are breaking like crazy in the region, but this spring remains in the running for third latest spring in KAXE Staff Phenologist John Latimer’s records.
Along with noting what is changing, John’s also noted what he hasn’t seen yet this spring, like green darner dragonflies, the spring azure butterfly and woodchucks.
The spring azure is a little blue butterfly that comes out for seven to 10 days and then disappears for another year.
Bud break galore
This week a listener sent in a photo of what John described as a short plant with a thick stem like broccoli. It has a cluster of white flowers at the top similar to dandelion, but white. John identified the plant as the sweet coltsfoot. He said it’s easy to find the flower when you check your identification book, but the leaves will look different later in the season.
Some of the female flowers froze during the cold snap, but others hadn’t opened their buds yet. Those survived the cold snap but may not get pollinated due to the dearth of pollen-producing flowers.
John’s silver maple tree is uncommon. Most maple trees are dioecious, meaning males and females are separate individuals. However, John's tree has a mix of male and female branches, and even has one flower cluster with both male and female flowers appearing within centimeters of each other.
John’s red maples haven’t flowered yet, though the buds are swollen. On average, they flower around April 19. Historically, they flowered on May 8, 2013 (the latest on record), May 7, 2022 (last year), and March 24, 2012 (the earliest on record).
Trees are changing, too
The male trembling aspens have dropped their flowers now, and the female flowers are turning green.
“Don't be fooled by the female aspens showing green and thinking that maybe they have bud or leaf break bud break. That is not the case,” John says.
The capsules holding the seeds are beginning to swell, and with binoculars this week, John could see just a hint of green so far.
Tamaracks are also beginning to show some green with pollen cones and seed cones developing.
Red maples are in flower and if you look closely, as all good phenologists do, you should be able to determine the sex of the red maple in your yard by looking at the flowers. If there is a bit of yellow showing, it’s a male. And if there’s some red little fingers sticking out, you’ve got a female with seeds on it.
Spring peepers and more
Spring peepers, wood frogs and the western chorus frogs have woken up and are calling. For those playing along at home, these songs of our amphibian friends are about 14-15 days late.
First bumblebee spotted
John’s wife Denise saw the first bumblebee last weekend and John identified it as the tricolored or orange belted bumblebee.
The birds are back in town
Listen for the “teacher teacher teacher” song of the Ovenbird. John claims you can hear this one at 60 miles an hour if you have your windows rolled down. Catherine from Grand Rapids reported Rose-breasted Grosbeaks and Brown Thrashers. According to John, “They are incredible singers.”
So many things to look and listen for right now. John suggests you get out and chase down the birds, peepers, dragonflies and butterflies that are emerging.
“When you find it, report it. Get in touch with us.”
