Notes from around Chicago outdoors. I juggled the usual outlet this week to match the lead photo.

FIELD NOTES

LAST WORD

‘‘Kind of nice I can come up here and give some good news [on yellow perch]. Things are looking up. That is the takeaway message.’’

— Steve RobillardLake Michigan Program fisheries biologist, noting the impact of the 2015 class of perch Tuesday at the Illinois-Indiana Sea Grant’s Lake Michigan Workshop.

BIG NUMBER

78.4 

Percent of release rate of yellow perch in 2017, according to surveys by the Illinois Natural History Survey. ‘‘Sign of a lot of small fish out there, potentially a good sign,’’ INHS’ Charlie Roswell said.

BUCK OF THE WEEK: UNPLUGGED

Bill Przybylski photographed the drop-tine buck above on Tuesday in Cook County. I asked Illinois deer-program manager Tom Micetich if drop tines are a factor in holding antlers late. He replied: ‘‘Drop tine would have nothing to do with antler retention. Antler drop is tied to declining testosterone levels after the breeding season.’’

Buck of the Week: Unplugged, the celebration of the stories and photos of live big bucks around Chicago outdoors, run when warranted on Sundays on the Sun-Times outdoors page. Send nominations by Facebook (Dale Bowman), Twitter (@BowmanOutside) or email straycasts@sbcglobal.net.

DALE’S MAILBAG

Q: ‘‘A few weeks ago, I was in Portage Park in Chicago and saw this big bird north of the park. Looking further, I swear it was a bald eagle. Have you heard of any other spottings on the Northwest Side? If it was, it was the first time this 60-year-old ever saw one in the city!’’ Jon Schultz

A: There have been eagle sightings on the North Side, even on the lakefront. Schultz replied: ‘‘I guess I’ll have to keep looking up! Not bad words to live by.’’ Yes.
