Urban wildlife

I've been neglecting 'my garden' this year.  The courtyard I planted up so lovingly three years ago is not quite gone to rack and ruin - just not not receiving the maintainance that it deserves (though my landscape architect neighbours said I chose the plants and planted up the courtard well :-) .
The last 2-3 days I have  been paying it more attention. Each time I have seen a blackbird flying in or out of the ferns that I bought back from Cornwall three years ago which are now well established.  It's a rare treat to see a blackbird in Brussels.  Guess she's built a nest there and that I should continue to beningly neglect the garden for the summer - unless until the chicks are fledged.
