Canadian bycatch

What is your view of introduced species?  I could live without pheasants (and the adders would thank us), but  love to see little owls.  If there were ring-necked parakeets locally I'd go and have a look.  Canada geese? In truth I probably see them as more of a nuisance species, and I've never headed out to snap them.
However my new project for this year is planned around an old estate lake and it is not short of CG's at present.  The access is limited but the accessible part of the lake is ideal for morning work, although to date the weather has largely messed up my plans.  I did get one morning a while ago when the weather and a free morning coincided, and I do think the site holds promise.
I'll hold back on posting my main targets as I think (hope) I will be able to build a better collection of shots (that pre-visualisation again) to post at a later date, but looking back at the snaps from that first session I really quite like the goose shots (although it's amazing/frustrating how the far shoreline is just at head height)

...... and one of a tufted duck.

 

From the calls I could hear in the background I also found a spot that might prove productive - know what it is?

Hopefully the main project will work out.  Here's one snap to start.

And the nest?  Long-tailed tit.  One for a remotely operated camera I think, but will need to make sure not to draw undue attention to it as I gather they are frequently predated.
