A Cooper’s hawk waits out the rain Wednesday in a subject alongside Six Mile Lake Road. Much of the latter half of the week noticed clouds, rain and colder temperatures.
Reports of hen flu spreading to dairy cows prompted me to surprise: Could deer contract the illness as nicely?
According to the Associated Press, the pressure of hen flu that has killed hundreds of thousands of untamed birds in recent years as of April 12 had been present in a minimum of 26 dairy herds in eight U.S. states: Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, Texas and South Dakota.
The virus, generally known as Type A H5N1, has been detected in a variety of mammals over the previous few years, however that is the primary time it has been present in cattle, in keeping with a number of federal well being and animal businesses.
Officials imagine cows seemingly turned contaminated by publicity to wild birds, however mentioned cow-to-cow unfold “cannot be ruled out.”
Farmers are testing cows that present signs of an infection, together with sharply lowered milk provide and lethargy. Animals that present indicators or take a look at optimistic for sickness are being separated from different animals on the farms. The animals seem to get well inside two weeks, in keeping with AP.
Deer are thought of cousins to the bovine household, a really huge group of cloven-hoofed ruminants that embrace cattle, yaks, bison, buffalo, antelopes, sheep and goats. The ones that feed in our yard recurrently are surrounded by quite a lot of wild birds additionally benefiting from the black oil sunflowers seeds put out day by day.
So if cows caught hen flu from contact with wild birds, would possibly deer be in danger?
Two officers with the Michigan Department of Natural Resources mentioned for now there’s no proof the illness has made the bounce from hen to deer.
The possibilities of a deer managing to attach sufficient with a wild hen that may be carrying hen flu “is pretty low,” mentioned Bill Scullon, DNR subject operations supervisor for the Upper Peninsula Region.
Even if it did occur unseen, it seemingly wouldn’t be deadly in deer, Scullon mentioned. Dairy cows that contracted the illness all seem to have recovered inside a pair weeks with no long-term unwell results, he mentioned.
Melinda Cosgrove, a laboratory supervisor with the DNR’s wildlife well being part in Lansing, agreed nothing has been reported to counsel deer may be prone to hen flu.
Despite the stories in dairy cattle, Cosgrove mentioned the incidence of hen flu seems to be waning. Her lab has acquired fewer useless birds submitted for testing, definitely nothing just like the summer season of 2022 when the illness hit migrating populations arduous, particularly waterfowl and raptors like bald eagles that will prey upon the sick birds.
She expects this season can be extra like final summer season, maybe even rather less, by way of hen flu exercise. While the virus stays current and circulating, hen populations may be creating a level of pure immunity, Cosgrove mentioned.
“We’ve reached the new norm,” she mentioned.
I’ve not seen any advisories to this point to point warning is required in feeding birds this spring and summer season, as was the case in 2022. Still, it’s at all times a great apply to maintain feeding areas raked to discard seed and different supplies that may have gone unhealthy and to recurrently clear feeders with a lightweight bleach answer to cut back different viruses or micro organism that may sicken birds as nicely.
Scullon additionally reminded the area that bears are again out, so it’s time to take these feeders in at evening in the event that they’re not out of attain. Having had bears daring sufficient to come back up on the again deck or entrance stoop on the lookout for a snack, I can say that’s good recommendation.

Spring’s advance had a little bit of a slowdown this week as cooler temperatures took maintain once more, although some indicators of development are positively round.
Several full skeins of Canada geese might be seen overhead early within the week. Spring peepers are noisy; no wooden frogs heard to this point, although I believe they’re on the market.
As to hen migration, a standard yellowthroat gave its “witchety-witchety-witchety” name, signaling a minimum of that warbler was again. Tree sparrows proceed to maneuver by, most sure for breeding in Canada.
Pied-billed grebes have combined with the mallards on Six Mile Lake this previous week. A stunning pair of blue-winged teal paddled by Thursday, however I didn’t have digital camera readily at hand.
Otherwise, few new arrivals might be noticed, a minimum of out at Six Mile Lake. A look on the Birding Wisconsin Facebook web site didn’t point out a lot new motion, both.
But it received’t take lengthy if the climate turns again to extra favorable circumstances.
The different main signal of spring has been the courting turkeys. One pair acquired busy proper in the course of Six Mile Lake Road. But more often than not, the females appear rather more intent on foraging, preening, ingesting — almost something however take note of the strutting, posing shows of potential mates. I ponder what does lastly win them over?

Quick update on the injured crow: After being absent a lot of the earlier week and the weekend, the crow has been seen twice, wanting in good well being, although it’s dropping a number of the flight feathers on the damaged wing. I proceed to place out further meals that’s accessible to the grounded crow the place I can. The darn squirrels preserve attempting to run off with the additional suet, so I’ve engaged on devising a system to maintain it in place at floor stage.
