Phenology is a science focused on observing and recording biological events from year to year and their relationships to the change of seasons and climate.
These are the “normal” phenology events we expect to see here and in the Madison area this month. We would love to hear about what you are seeing on the grounds of Holy Wisdom Monastery. Please comment on this post with what you are observing, where at Holy Wisdom and the date you observed the event.
I have kept monthly phenology records for many years and the following are from my June entries. Some events occur in late May also.
- Bird migration is over
- Chorus of birdsong most of the day
- Nesting season
- Insect sound and activity increase
- Parade of prairie flowers
- Trees and shrubs bloom
- Summer solstice June 21 (over 15 hours, longest day of the year)
- Resident and summer visitors sing, mate and raise young. About 80 species nest in the Madison area. The list includes several kinds of wrens, sparrows, swallows, thrushes, vireos, woodpeckers, and flycatchers. Also, gnatcatcher, oriole, catbird, thrasher, rose-breasted grosbeak, indigo bunting, hummingbirds and many more. A few kinds of warblers nest here.
- Dickcissels arrive (a very late migrant)
- Young owls continue to beg and start to fly
- Ducks and geese molt
- Wood thrush sing at dusk
- Last “peents” and sky dance of woodcock

- Deer shed gray winter fur and grow red-brown summer coat
- Look for velvet-covered antlers on male deer
- Young are active (fox, coyote, skunk, flying and gray squirrel, rabbit, raccoon, opossum, mice, woodchuck…)

- Mosquitoes feed and are fed upon
- Dragon flies hatch and patrol for mosquitoes and other insects
- Japanese beetles (Popillia japonica) emerge end of the month
- Deer or black legged tick larvae and nymphs take blood meals and can transmit Lyme disease. Take precaution!
