A windfall of cherries

Hollyleaf cherry (Prunus ilicifolia)

A year and a half ago we were bumping along in the pickup when a bulb above Random Truth's head suddenly filled the cab with bright light.

"How about setting a cam in that patch of hollyleaf cherries on Gillam Spring Road?".

According to the scatological calendar it was that time of year again: the landscape was littered with carnivore scat, as it always is, but now most of the scat was chock full o' nuts, which means the critters were pigging out on wild cherries.

You can't mistake the pit of the hollyleaf cherry for anything else. As cherry pits go, they are BEEEG.

"Good idea, RT".

I am fond of windfall sets, but Craig was non-commital.

"You never know who's gonna show up at the cherry patch", I continued, "and ringtail might make a surprise appearance.

If indeed Craig was lukewarm to the idea, the mention of the elusive Chimineas ringtail changed his mind. He headed for Gillam Spring Road.

Well, we were too late in 2010. The cherries were past fruiting.

But we didn't forget.

A bumper crop of hollyleaf cherries called us back in 2011, and we set a camera at the assigned thicket.

We fetched it a month later and found over 400 photos.

The most common visitor (151 photos) was our old friend the wood rat. 

The wood rat (probably Neotoma macrotis) hauling a stick , which it dropped a few moments later.

In two shots the rodents were carrying cherries, in three shots they were hauling sticks, and the rest of the time they were running around or exploring. 

Gray foxes appeared on 4 occasions, and there was one photo of a bear's backside, clearly detectable only after photoshopping.

There were no surprises at set 530; in fact it was a bit of a disappointment.  

I knew the wood rats would be there; they're everywhere.

But I thought they would tell us a different story, a story about fulfilling their manifest destiny as seed dispersers.  

Not this time.

If we try again, with cameras at several patches of hollyleaf cherry, wood rat might give us a surprise.

But there are a lot of other subjects worthy of camera trapping, and wood rat can always be relied on for a cameo appearance.

I have tried the "choke cherry" myself - not as tasty as you'd like, but a good source of sugar. We see bear scat just full of pits. Sometimes fox, but I always think it must be a bit uncomfortable for them!

Thought that set would be a lot more interesting. Darn animals and their unpredictability! :)
