Hellgrammites and More Signs that Spring is Coming

I've recently been poking around logs a little, but it's still a little early to find much. On my walk at lunch today at Strathroy CA I found Hellgrammites also known as dobsonfly larvae under an old railway tie in that is being used as a pedestrian bridge.  It's hard to see the scale, so I linked to a web photo with an individual in a woman's hand. These inverts make excellent bass bait. They are also relatively pollution intolerant, so a sign of decent water quality. Not surprising as the wet area where they were found seems to be fed by groundwater (note the rust colour formed by the oxidation of iron as the the water surfaces). I will re-visit the spot someday when I plan to go fishing. Also, the skunk cabbage is coming along nicely. According to Wikipedia: "Skunk cabbage is notable for its ability to generate temperatures of up to 15-35°C above air temperature by cyanide resistant cellular respiration in order to melt its way through frozen ground, placing it among a small group of plants exhibiting thermogenesis." I noticed one to the larger skunk cabbage shoots I have been monitoring is gone. I didn't realize that wildlife ate them, but can't think of another reason it would be missing.

Hellgrammite

Hellgrammites are another insect with an incredible life-cycle.  According to Wikipedia "After a few years of living and growing underwater, the larvae crawl out onto land and pupate. They stay in their cocoons over the winter and emerge only to mate. Upon emerging, they live for only seven days."
This image from the web shows the hellgrammite head under a microscope.

Icey Walk at Strathroy CA


Aquatic Sow Bug - Feeds on detritus. Can live in oxygen poor environment, generally a pollution tolerant group.

Lot of pretty ice formations.

Frozen raccoon prints

This frozen prints were sparkling in the sunlight - not capture too well here.

Not much to see this morning despite the sun.  There were about seven white-tailed deer, downies, hairies, chickadees and the other usual winter creatures. Photographed some  crisp raccoon and meadow vole tracks.  One aquatic sow bug under the ice.

Coldstream Conservation Area

Andrew and I put on boots and played in the river all afternoon.  The sun was shining and it was glorious.  One of the coolest sights was little orb shaped ornaments of ice hanging in the water.  No good pictures, as I  broke the prettiest one off trying to get close.  Inspired by a blog about winter herping, spent time turning over rocks and logs looking for mudpuppies

Ice scupture hangs like Christmas Tree ornament
Floater (?still need to look up) shell (top) and live mussel (bottom)



. Five fishes were seen in the clear water: darter, sucker, pumpkinseed, creek chub, and a random minnow.    Also, tried looking for mussels, but only found one live mussel and a scattering floaters(?) and papershell shells. Both these mussel species are ubiquitous and generally indicate poorer water quality. There were lots a invertebrates too including odonates and mayflies (indicators of better water quality).  I thought about bringing them home for my aquarium guests (snake, fish and turtle) to snack on, but decided that they belonged under the rocks where I found them.  By 4:30 we started for home mud covered, with wet feet and cold hands.  Nonetheless, I couldn't resist taking a detour to see the Snowy Owl at Seed Rd. We were not disappointed: Andrew got a new life bird and it was the perfect primer for us watching The Big Year.

3 Pileated Woodpeckers, Strathroy CA


 The conditions were great for following tracks and dinner scraps right to animal homes today.  First I saw where a squirrel had eaten some Norway Spruce seeds. It was funny to note how many animals use a large dead tree as a river crossing. It is an enticing tree that I have tentatively tiptoed across  more than once. (I guess not looking too nimble, since last time trail walkers stopped to advise against it.) Next I followed some (coon?) tracks right up to a burrow and took some pictures down inside. Not too interesting.... Then I heard some tapping.  Then more.  It started echoing all around me.  I spied a total of three Pileated Woodpeckers in the silver maple swamp.  All within 100m of each other. Below you see two in a (very blurry) photo less than 2 meters apart.

Kindred Spirit

In the winter when the sun sets early and it is too cold to go out exploring in the dark, I sometime resort to creeping other blogs. I stumbled on "swamp things" google searching five-lined skink scat and a found Southern Belle of my own heart.

Early Spring????

The weather is so mild we are all hoping for spring, but could it be true?:
  • Today Brian Salt of Salthaven Wildlife reported seeing a nursing squirrel!
  • Tundra Swans have arrived south of Kettle Point about a month early (http://foxfm.com/sarnia-ontario-news/early-arrival-for-tundra-swans/) 
  • Red-winged black bird observed in London (http://tech.groups.yahoo.com/group/midd_elgi_observations/message/1803) 
  • Turkey Vulture sightings (http://ontbirds.ca/pipermail/birdalert_ontbirds.ca/Week-of-Mon-20120206/029541.html) 
  • I saw a Red-tailed hawk with nesting material in its talons last Saturday

I hope that all this early spring weather doesn't switch to abnormally cold temperatures that confuse the wildlife even more.

Great Horned Owl? Strathroy Conservation Area

These photos are terrible, but I so rarely see an owl at the Strathroy Conservation Area I couldn't resist. This individual was near the Norway Spruce on the west side of the resevoir at about 5:30pm yesterday. The owl was fairly large - I would guess 15" tall, with tufts at the ears.

Approximate Location:

Snowy Owl North of Strathroy

Here is a Snowy Owl that has been hanging out North of Strathroy in the area around Egremont Rd. and Seed Rd. Yesterday we saw two.
