Critters gotta to eat, too

 Now that February is finally drawing to a close, we've been getting the occasional warm-ish day, causing the frozen ground to soften up a bit. I was out in the yard the other day and I noticed numerous little piles of mud erupted out of the grass. These piles of mud are joined by long ridges of disrupted soil, soft and mushy underfoot. Are you curious yet? This is the handiwork of moles. I suppose most homeowners would get upset over this defacement of their grass, but it really doesn't bother me that they're out there busily tunneling across our yard. Moles are not rodents and they don't hibernate. They're active during winter and they are insectivores - they eat insects, worms, centipedes, and the like. They're actually helping us by eating various pest insect grubs that are tucked underground, among which are Japanese Beetle larvae. Thank you, moles!
 It pains me to see the various poisons in garden centers that are used to kill not only insect pests, but moles too. I prefer to let nature operate undisturbed as much as possible, plus I think moles are interesting little critters.
 One species of mole we have around here is the star-nosed mole. Talk about bizarre - this thing is simply crazy looking! Moles are odd looking to begin with, but the star-nosed really kicks it up a notch. It looks like someone gave it one of those cartoon exploding cigars. Here is a good article about them, with photos. While I have seen star-nosed moles out there now & then, the molehills were more likely the work of the eastern mole, the kind that comes to mind when you think "mole". But anyway, why would you want to kill any mole? They're fascinating ( as all creatures are to me ) and they're just doing their job out there.

I extend this same philosophy to spiders and snakes - they're just doing their job. They gotta eat, too. I personally have a strong aversion to spiders. Okay, well, they freak me out. All right, I admit it - they make me scream and jump around as if I grabbed an electric fence... But that's only when I suddenly see one. Once I know where a spider has set up housekeeping, I leave it alone to make a living - giving it a wide berth, mind you. ( This only applies to outdoor spiders. If they're in the house, I'm sorry to say they are, er, disposed of. )
I think spiders and snakes are just as fascinating as any other critter. Last year I was trimming back a clump of irises when I was startled ( okay - I screamed. And jumped around. ) by a large wolf spider in between the sheltering leaves. After I recovered my nerve, I noticed it was sitting on its egg case. Believe it or not, I got my camera & documented it. I liked how it was guarding the egg case. So I worked around it and left those few leaves standing there, which served the double purpose of saving the spider and avoiding putting my hands anywhere near it. Eventually, it moved on. But there's more of 'em out there - LOTS more - doing their jobs and eating insects.

As to snakes, we leave them alone too. I'm not freaked out by snakes like I am by spiders. I used to catch them when I was a kid. We never kill snakes. ( I hope you don't either! ) They're another helpful creature to have around the yard & gardens, since they eat all manner of things, many of which are garden pests. We commonly see garter snakes and black rat snakes here. We see garter snakes quite often around our yard. I frequently come across one as I'm weeding the landscaped areas. We see them all the time in the vegetable garden, which is great since insects are a large part of their diet. It's nice to know that they're out there patrolling for pests and helping us.

 We don't see black rat snakes as often - maybe two or three times a summer - often enough to know they're out there. These snakes are quite large, often 6 feet long. They eat a lot of mice and chipmunks. Unfortunately, they also eat birds. But that's part of nature - snakes gotta eat, too. You might recall my first blog post about bluebirds - we install snake-proof guards under the bluebird boxes. Yeah, snakes gotta eat, but we put the bird boxes there so we have to be responsible about it!
 One summer Mr. Curious & I were doing yard work when suddenly there was a shrill racket and commotion in one the rhododendron bushes. Robins were screeching and fluttering around the bush. I guess you know where I'm going with this... The robins had a nest with young in there and a rat snake had found it. By the time we got close enough to see it, the snake was coiled around the nest - and the young robins. It sat there looking like a nightmarish fist clenching the birds. Beaks protruded from the coils at different angles. Rat snakes are powerful constrictors. We let nature take its course. At first it was horrifying. I hate to see any animal die. But it's life, too. So we crouched there and watched. Then I ran for my camera. It was actually an awe-inspiring spectacle. And it's astonishing how a small snake mouth can unhinge and consume a nearly grown robin! The snake ate 3 birds. Below is a picture of it with its body stretched out of proportion, stuffed with young robins.

It's also cool how a creature with no appendages can expertly climb trees and shrubs. I have to say that this was one of the most amazing things I've ever witnessed in nature. Hard to watch, but amazing. Shocking, perhaps, to some of you. But nature needs predators to keep things in check. If not for moles, spiders, and snakes ( not to mention bats and countless other creatures ) we would be completely overrun with bugs, mice, and what have you. It would be impossible to grow anything, diseases would spread - it would be a disaster of epic proportion. Usually when you think of predators, you think of the big mammals like tigers & wolves. But you don't need to watch a documentary to see predators in action - just think smaller and you'll see all the action you ever wanted to see. Thousands of little life & death dramas play out every day in our yards & gardens. That's how it is, and how it should be. Critters gotta eat. And their quest for food can provide the curious and observant person with some incredible experiences! I'm quite happy to live here, thank you very much, with a lumpy lawn, spiderwebs festooning the gardens, and snakes hanging from the shrubs. So, who's ready to come over for a cookout this summer? Ha!

Bluebirds through the window

I've been observing bluebirds out my window. They arrive in small flocks of 6 - 10. They flutter about the yard, trying out different perches, nabbing a wayward insect or two, and then they begin to land on the nest boxes. It's fun to watch them as they check out the boxes. I can easily anthropomorphise their behavior as they flick their wings and chatter to each other: "What do ya think? I dunno, let me go in...Please do! After you..Thank you,Yes, okay, this one's not bad.." and so on. In fact, I can imagine them chatting back and forth in the manner of those polite gophers from the old Looney Tunes cartoons. But I digress.
In the winter months, bluebirds form small flocks and travel about foraging together. They will use empty nest boxes as a communal roost at night when the temperatures really plunge - as they tend to do during our long, dark Pennsylvania winters. I like to think of these as 'our' birds, although there's no way to know for sure if they are, in fact, birds fledged from our nest boxes.

Looks like they're trying to reach a consensus.
 
Wing-flicking - "Over here, this one looks great!"

Some background info would be helpful.We put up the nest boxes years ago, as we live in ideal bluebird habitat: open fields bordered by woodlots. We've hosted nesting bluebirds every year since. They always raise two, sometimes three, broods. We love 'our' bluebirds! They are very personable - as birds go - and beneficial to have around the yard since they feed on insects, caterpillars, and the like.

Our first two nest boxes were mounted on a fence post and a tree. Both are terrible ideas. It's amazing how many different creatures can and will climb in order to reach a tasty meal of eggs or nestlings.The final straw came when a squirrel deftly reached into the tree-mounted box, pulled out the nestlings one by one, and devoured them. Murdering squirrels?? Waaah! Enter our current predator-proof mounts.The boxes are on metal poles with a homemade predator guard below.

If you plan to host bluebirds, do yourself a favor and install the boxes on a metal pole with a guard underneath. Here are plans for a stovepipe baffle. That website, Sialis.org, is an excellent and complete resource on being a landlord to bluebirds and other native cavity nesting birds. I might mention that I didn't touch on the subject of English Sparrows here - that is a subject for another day when I'm in more of a ranting mood. Suffice it to say that the predator baffles don't help with that problem. And problem it is, with a capital P which rhymes with G and that stands for Gun.... Stop right there! Before you write me off as a yee-hawin' nut - hear me out. I am not a shoeless, gun-totin' old Ma with a chaw in m' lip - if you peruse the Sialis website, you'll see where I'm coming from and what a dire threat the sparrows pose to Bluebirds.

Meanwhile, off I go to waste some more time, staring out the window at the cute antics of MY bluebirds!
