Showing signs of spring

I'm away for the weekend, and i suspect as a result i'll miss some interesting arrivals to the reserve.
I went down today and the daffodils have started to bloom. I also saw my first red-tailed Bumblebee of the year. A sure sign that Spring is edging ever closer! I suspect it won't be long now till we hear the familiar 'chiff chaff, chiff chaff' of the first warbler arrivals to the reserve.
Our male mute swan has returned to the reserve as well. Here's hoping he's soon joined by a female and we get another successful year.
The most interesting sighting today was just as i was about to get into the car and drive off. I heard a very loud croaking noise and when i looked up, there was the familiar diamond tail of a Raven! They're not particularly common in this area, so it was good to see. I only saw ravens once last year at Cullaloe, so if i see it again, i'll have improved on the record!Anyway, i'm now off on a trip to Ayr for the weekend for College. If anyone is planning on visiting the reserve this weekend, please feel free to let me know what i miss!
On that note, if you see something that isn't on the species list, I'd be grateful if you could let me know so i can add it to the list.
