I change bird water often and always tap
Beautiful day again today and I have only just come in from the garden.
It's crazy to think I can do my housework in half and hour and yet the garden takes all day 
List of jobs done today included turning my three compost piles, watering some newish plants that are flagging, watering veg, weeding out a crazy amount of self seeded Nigella
, mowed-raked and mowed the lawn again, pricked out my basil seedlings into plugs, took cuttings of my alpine Phlox and divided some Cowslips and Doronicum to make a better drift for next year's spring display.
Also, forgot to mention yesterday's drama in the garden. One of four local Magpies was sticking his head in the guttering looking for Sparrow chicks whilst the tiny Sparrows chirped madly at the brute and when I went to the shop in the afternoon, I saw one of four Magpies trying to raid a Blackbird nesting in a conifer but this time the female bird was not having any of it and screaming wildly in defence of her eggs/chicks (the male was hopping about doing his teritorial dance) until it flew off empty beaked. I know its only nature but I was a little shaken up.
Today the crows arrived in their gang and bullied the magpies for the prime nesting sites so I guess every bully has a bigger thug to put up with.
