Spotted Flycatchers are back!

Although we went on a twitch today to see a Broad-Billed Sandpiper it was no where near as exciting as finding my  (I consider them my own) 2 Spotted Flycatchers back from their African travels and back at the same nest box in Normanby Park as last year - so the worry now begins, will they be successful or will one of the 50+ Squirrels find them!  Also not quite as exciting but blooming good was the discovery of a third Nuthatch nest also in the Park.
