Here’s the elk calf!

June 5, 2026 • 10:30 am

Did you spot the elk calf in Matthew Hill’s photo this morning? Here it is!

When I asked Matthew how, in the tagging process, he found the hidden calves, he replied:

Typically the cow has a vaginal insert transmitter that comes out when the calf drops, which allows us to pinpoint the birth location. Several hours later the cow and calf move a short distance off the birth location where the calf conceals itself. Say, within 50-500 m. When we arrive, the cow leaves the area but will come back within 4-5 hrs. We systematically survey the area looking for it. Really hard game of hide and seek!

Example of an “activated” vaginal insert transmitter (“vit”) recovered at birth location.

More photos from the tagging process:

 

More: a wolf attacked another calf, but mom apparently drove it off. Matthew:

I’ve attached pics from yesterday of a five day old calf that survived a wolf attack only hrs before we arrived. Very lucky calf.  It must have been a single wolf, and the cow was able to fend it off. If two or more wolves, the cow would have bailed to live to breed another day.

Spot the elk calf!

Reader Matthew Hill sent some photos taken during his tagging of elk calves (Cervus canadensis), and one of them qualifies as a “spot the. . . ” photo.  Can you spot the elk calf, hiding from predators inconspicuously?  The reveal will be at 10:30 Chicago time, along with other photos from Matthew’s endeavor. His words are indented:

I’m currently involved in tagging elk calves in northern Wisconsin. I thought one of today’s tags might be a fun one for an I spy post. Not super difficult.  It’s a two-day-
old female.

Can you spot it?  You can tell us in the comments if you did, but please don’t say where it was. Again, reveal is at 10:30 a.m.  Click the photo to enlarge it.

 

Spot the tree frogs!

It’s been a long time since we’ve had a “spot the. . . ” challenge, but Robert Lang submitted one. His caption, indented below, tells you that there are three frogs in the photo. Can you spot them all? There will be a reveal at 11:30 a.m.  Robert wrote this:

It’s been a while since you’ve had a “Spot the…” photo, and I think this one qualifies. Here we’re looking for California Tree Frogs (Pseudacris cadaverina). The first one is obvious. The challenge is to spot the other two (total of three). This was taken in the Arroyo Seco in Southern California, on the way up the creek bed to Royal Falls.

Of course you must click the photo to enlarge it for starting your search.  PLEASE DO NOT GIVE THE ANSWER IN THE COMMENTS so that everyone can have a go without pointers.

 

Here’s the hummingbird!

Did you spot the hummingbird in Athayda Tonhasca Júnior’s photo this morning? Well, here’s a photo and and video reveal.  This one was fairly easy, I thought:

The first video reveal we’ve had:

 

His ID:

The bird looks like a planalto hermit (Phaethornis pretrei), but I don’t put any money on it. This group is notoriously difficult.
