Earth Day Mini Bioblitz 2007

The Song Sparrow performed a special concert this morning

I did not register for the Blogger Bioblitz due to a lack of expertise and time. In the spirit of the event, I decided to spend one hour in the old landfill site recording the more obvious and slightly hidden things around me. I chose not to wade through the vernal pools or turn over logs and stones looking for insects. We have had warm weather with temperatures around 20C the last three days. Because of the very cold weather during most of April, the plants and trees are a little behind schedule.

I picked a small corner of the field that included a vernal pool, meadow, and a small deciduous bush, containing mainly oak and maple trees. Houses, malls and roads surround this entire area in the suburbs of our city. I went out from 9:15 until 10:15 in the morning with my trusty assistant, Dakota. I have spent a number of hours in the area this spring and knew where to look for a variety of birds.

I have seen where the Kildeer are nesting, but if I hadn't, it would heve been hard to find them today as they hid in the grass.
Here is the list of birds, animals and plants I identified.

Red-winged Blackbird 20+, Kildeer 2, American Robin 20+, Canada Goose 4, Starling 5, Mallard Duck 4, Common Grackle 2, Downy Woodpecker 1, Song Sparrow 2, Brown headed Cowbird 1, House Sparrow 20+, Brown Creeper 1, Eastern Phoebe 2, American Kestrel 1, Chickadee 1, Gold crowned Kinglet 2, Cedar Waxwing 4, Northern Cardinal 2, American Goldfinch 4, Dark eyed Junco 1, Red tailed hawk 1, House finch 4, Crow 2, Mourning Dove 3.

We also discovered
Groundhog 1, Cottontail rabbit 1, Grey Squirrel 2, Black Squirrel 1, Field mouse 1, Garter snake 1

Dakota found the snake and I am very pleased that I did not panic and was able to take a picture of it at fairly close range. (well, with a little zoom!) It seems my snake phobia may be decreasing with my understanding of their place in this little ecosystem. If the dog had not seen the snake, I may have been startled by stepping on it as it blended in so well with the dead grasses.
There were very few flying insects. As we returned home I saw three dragonflies. This afternoon there are swarms of flying insects in our yard that were not around earlier in the day.

Green shoots were coming through dead grass and leaves and I did not try to identify them. The city had seeded the entire site with grass over 25 years ago, but native species now dominate the meadow. The bush had many Trout Lilies starting to poke above the ground and there were a couple of Trillium shoots as well. I know this area has an abundance of Trillium blooms in May.

The vernal pools are shrinking rapidly as we have not had a lot of rain or snow this month. I believe these are Spotted Salamander eggs. I noticed plenty of bubbles in the shallow water as gases escaped from the frost free ground. I don't know if this is normal in swamps, or if this is caused from methane created by the garbage below this site. I did take a movie of the bubbling and will post it if I can figure out how to do it.

While I saw nothing unusual, I was surprised at the length of the list compiled in such a short time, so early in our spring season here in South Western Ontario. I look forward to reading about the findings of more experienced naturalists as they participate in the Bioblitz.

Picking a spot and observing life for an hour--the perfect thing to do on a spring day that finally feels like spring.
Is your snake phobia a remnant of having grown up in S. Africa?

Mary said...

Oh, I think you do have the expertise, Ruth. Time is a factor, though. I'm happy for you to see so much in a short time. You have a lot to offer on Earth Day.

LauraHinNJ said...

You did see lots! Amazing, really, in just an hour's time.

Larry said...

Sounds like you have yourself a gem of a spot.I like making repeat visits to special places like that.

Jayne said...

That's quite a list Ruth. Sounds like you all had a fun adventure.

Cathy said...

Other more experienced naturalists will be wading in, but none will do a better job of sharing the sheer pleasure of being out on a lovely Spring day with their able canine friend.

KGMom- Yes, I am sure my snake phobia is from Africa where I remember a mamba and a puff adder being found in our garden. And the Snake Park in Durban was what nightmares are made of...

Mary- I hope to continue to learn every day. Yes, there never is enough time for all I want to do!

Laura- I surprised myself. So many of the birds are so common, I hardly notice them. Like the crow and 2 mourning doves I forgot to write down.

Larry- Who'd ever think that an old dump would be a gem of a spot!

Jayne- I would be thrilled to see the variety of birds that come to your yard. You must have quite a list yourself.

Cathy- Yes, enjoying the beautiful day was the best part of all. All the more appreciated because of the delay in spring's arrival.

I think you have a super list, especially considering the locale and the period of time. Very glad to see that you joined in on blitzing an area in your neighbourhood!

Thank you Tom and Bev. You are both an inspiration and source of so much interesting knowledge.
