Annual Visit of Waterloo Region Nature to SpruceHaven

14 September 2019

Leader: David Gascoigne

Club members participating: Miriam Bauman, Shirley Bauman, Betty Brechun, Theo Byrne, Catherine Campbell, Lynn Conway, Daniel Entz, Fraser Gibson, Anne Godlewski, George Greer,  Brad Hale, Cathy Hale, Bill Hall, Victoria Ho, Dale Ingrey, Nina Ingrey, Adriaan Kemp, Barb Kemp, Denise Leschak, Hugh McCaul, Louise McCaul, Alan Morgan, Anne Morgan, Janet Ozaruk, Meg Slater, Frank Steinmoeller, Marj Steinmoeller,  Henriette Thompson,  Selwyn Tomkun, Don Voisin, Mary Voisin, Andrew Wesolowski, Lorraine Wesolowski, Stephen West, Susan Youngson.

Guests: Nicholas Bauer, Sarah Colter

     Judging by the impressive attendance for this annual outing I can say with confidence that this is the most anticipated event on the Club's schedule. There was a nucleus of regulars supplemented by many members visiting for the first time, and a couple of guests.



      Everyone is not in the picture above, but it gives you an idea of the level of participation.
     We always begin our day's activities in the barn which houses our Barn Swallow (Hirundo rustica) colony, which is where it really all started.




     This majestic old structure is looking quite grand this year having received  a fresh coat of paint and repairs where necessary.
     It is a great pleasure for me to have so many people interested in what we do and to explain the full scope of our monitoring and research activity.





        Newcomers are filled with knowledge before they leave and veterans of this event are always happy to learn of improvements in tracking devices, and to hear of discoveries we have made during the season. There is no doubt that these birds still hold many secrets we have yet to discover.
     The swallows have all departed for South America, but the nest below reminds us that they called SpruceHaven home for another breeding season. Given the conflagration in the Amazon, and the uncertainty of the conditions awaiting these migrants, it is unclear how many will survive to return next spring. It is with no small measure of sadness that we contemplate the  future of Barn Swallows and other aerial insectivores, when it seems that anthropogenic interference and continued habitat degradation and elimination, renders their existence ever more precarious -  to say nothing of the poor choices we continue to make in electing our political "leaders."



       We moved outside to continue with our walk and it seems that Selwyn Tomkun was anxious to point out something to me.


  
     We have installed numerous boxes for Eastern Screech Owl (Megascops asio) and have had a reasonable level of success in attracting these charming little owls to use the boxes as winter roosts, but so far none have bred in them.



     We continued with our walk.




     And there was more to do in terms of explaining the various programmes we have underway at SpruceHaven and the success of our nest boxes.



     This past season Tree Swallows (Tachycineta bicolor) and Eastern Bluebirds (Sialia sialis) fledged record numbers of young and we also had great success with Black-capped Chickadee (Poecile atricapillus) and House Wren (Troglodytes aedon). We continue to be motivated to help cavity-nesting species who find fewer and fewer natural nest sites and we have plans to erect more nest boxes this fall in readiness for next year's breeding season.
     We were lucky to have Fraser Gibson on hand to explain the features of the latest advances in beehives.





     The "jewel in the crown" this year is the conversion of approximately forty acres of farmland to native grassland. Soil samples were taken and the land seeded with the mix of plants that would have been characteristic of a tall grass prairie at the time of European settlement of our area.



     It looks a little weedy right now, but as the new growth establishes its dominance this will start to change. We have a reasonable expectation that by next year we will attract Eastern Meadowlark (Sturnella magna), followed by other grassland species in succeeding years. It is a very exciting prospect.
     Already I have noticed an increase in Savannah Sparrows (Passerculus sandwichensis), and Barn Swallows and Tree Swallows were seen hawking insects over the field , and Common Starlings (Sturnus vulgaris) were feeding on the ground in large flocks . When Kevin and I were banding last weekend Horned Larks (Eremophila alpestris) flew overhead.
     


     There was more to explain!



       Everywhere is awash with Canada Goldenrod (Solidago canadensis) at this time of the year, and it is both beautiful to see and provides rich foraging for butterflies and other pollinators.




     A Wooly Bear Caterpillar was seeking a place to hibernate for the winter; it will pupate in the spring to emerge as an Isabella Tiger Moth (Pyrrharctia isabella).



     These fungi on a tree were very interesting, but I am afraid that I am unable to identify them.



     We went into the woodlot to introduce everyone to our salamander monitoring project.



      I was lucky that under only the second board I turned over there was a cooperative Eastern Red-backed Salamander (Plethodon cinereus) for all to see.



  
          It is a measure of the deep interest that our group has in the natural world, that very few participants had dropped out along the way, and those that faltered did so only due to mobility issues and not from any lack of interest.



     It was time to head to the house for coffee and refreshments and we wended our way across the future grassland, slowly I might add, as everyone stopped to check out every treasure that revealed itself.



      I am sure I am not the only one who cast a glance across this rolling terrain with visions of a tall grass prairie blowing in the wind a few years hence.
      Everyone enjoyed warm Westfall/Hill hospitality and relived the events of the day and marvelled at just what SpruceHaven has come to mean to us all.






     Dave, Sandy and Jamie have proven themselves to be true visionaries and custodians of nature. Their commitment to habitat restoration and the preservation of the natural world extends far beyond what one might reasonably expect from even the most dedicated conservationist. As one who gets to deal with them every day I am constantly reminded of their largesse, the magnanimity of their philosophy and their fundamental decency.
     I know that you will all join me in saluting these champions. It is a privilege to have them in our lives.

Laurel Creek Conservation Area

Laurel Creek Conservation Area
Waterloo, ON
4 August 2013

    I enjoyed a stroll through Laurel Creek Conservation Area this morning and found my first Northern Mockingbird ever in Waterloo County. Unfortunately I was unable to get a picture of it! 
    Common Starlings Sturnus vulgaris seemed to be everywhere one looked and they have obviously had a very successful breeding season. From treetop to grassy meadow this species was easily heard and seen.




    The collective term for a gathering of crows is a murder and these American Crows Corvus brachyrynchos were perhaps gathered to discuss matters of life and death in the crow world.





    A Spotted Sandpiper Actitis macularia was very cooperative at the water's edge, and I wished I had the skills of my artist friend Barry Kent MacKay to enable me to render the exquisite palette of colours formed by the reflection of the shoreline vegetation.



    A Wooly Bear Caterpillar was crossing the road at a good pace. This is the caterpillar stage of the Isabella Tiger Moth Pyrrharctia isabella, and it has a very interesting life cycle. It hibernates each winter, virtually shutting down its body and protecting its tissues with a cryoprotectant. These caterpillars can re-emerge and hibernate again for several years before finally attaining adult moth status.
