A real toadstool

      I think that most people, in the English-speaking world at least, have heard the word "toadstool" and have probably used it too to describe some form of mushroom. In fact, I would be curious to know whether other languages have a similar expression.
     From my knowledge of its usage in English it is generally used to describe an inedible type of fungus found in the forest.
     I cannot recall every having seen it as a toadstool literally, until I came across this American Toad Anaxyrus americanus resting on bracket fungi.


     The forest was full of toads, with many tiny ones, but this full grown specimen was the pride of the bunch. It was very co-operative as it posed for pictures, even turning to give us a different view, without leaving its seat.


     Nature is wonderful! Every day's exploration holds a potential surprise; I wonder what my next new discovery will be?

Migrants at rare Charitable Research Reserve on 23 August 2015

     Every Sunday morning, spring and fall,  Miriam and I monitor a route at the rare Charitable Research Reserve in Cambridge, ON. The statistics garnered from our walk, when combined with those of other monitors in different parts of the reserve, provide a detailed summary of the species using rare for breeding, or passing through as migrants.
     An integral part of this data collection is provided by the teams of bird banders and we always check in with Kevin Grundy and Ross Dickson before and after our walk. Here are Kevin and Ross busy at their banding station.




     By the second half of August many warblers, flycatchers and thrushes are already migrating and several interesting species had just been retrieved from the nets when we arrived, including this Least Flycatcher Empidonx minimus.



     Canada Warbler Cardellina canadensis is a species whose numbers have plummeted in recent years so it was especially pleasing to see this one captured in the nets. Unfortunately, for some reason, most of my shots of this species were blurred and I cannot offer you a frontal view.





     The images below of a Northern Waterthrush Parkesia noveboracensis give a much better view of the bird.




     None of these birds had any noticeable level of fat deposition, so they will still spend a little more time here before they embark on the final stage of their migratory journey.
     For a while I was beginning to question the value of banding in an era when advances like satellite tracking of birds began to deliver such a wealth of information, often with more detail and precision than banding could ever do, and in real time. I mentioned this doubt to Phil Slade, a UK bander with whom I have regular internet contact, and he sent me this link to an article by Ian Newton, surely one of the finest ornithologists Britain has ever produced: http://britishbirds.co.uk/article/bird-ringing-still-necessary/  I think that it is convincing in its endorsement of the value of banding as an ongoing tool and it would make valuable reading for anyone interested in this practice.
     While on our walk we saw a couple of Rose-breasted Grosbeaks Pheucticus ludovicianus including this male moulting into its drab winter plumage.




     In addition to the birds we encountered this really impressive growth of bracket fungus, the largest I have ever seen. ( My good friend Janet Ozaruk advises that this fungus is Shelving Tooth Climacodon septentrionale. Thanks Janet!)
     

     On Thursdays I monitor another route at rare. I wonder what new species will be found then.

Black-billed Cuckoo (Coulicou à bec noir)

     Every Thursday and Sunday I monitor a route for rare, a local land trust and research facility. Miriam always accompanies me on the Sunday route and before actually embarking on our survey we always check in with the guys who are operating a banding station. Last week we arrived just as they had banded a Black-billed Cuckoo Coccyzus erythropthalmus.



     This species is unusual in that it feeds readily on tent caterpillars, a prey which most other species avoid. Periodically, tent caterpillars which are moderately sized species in the genus Melacosoma and in the moth family Lasiocampidae, are irruptive and this year appears to be one of those times.




     Subsequently, Miriam and I heard a Black-billed Cuckoo during our walk and three others had been banded last time I checked. So, there appears to be a correlation between a tent caterpillar outbreak and the abundance of Black-billed Cuckoos. Quite how this knowledge becomes known to the cuckoos I am unable to explain.
     Mayapples Podophyllum peltatum are now in flower and the forest floor was adorned with this species.




     Bracket fungi, which for some reason hold a special fascination for me, were commonly found, some quite magnificent in their size, colouration and structure.



     These organisms are among the many groups of fungi that comprise the phylum Basidiomycota. Ultimately they cause the death of the tree, thereby returning its nutrients to the cycle of growth in a healthy forest.
