Woken up by my Yorkie this morning and went to let them into the back garden. Usual routine is he has a wee sniff round the garden and does his business and I feed the birds, some on the grass, bird table and refill hanging feeders. Except this morning I went to the table where I keep the tub holding my 3-4 litres of bird food and it wasn't there. I just stood there going what, where is the bird food? It was gone! Then I spotted it about 20 metres away upside down with a broken lid. So my question to you is what type of bird could carry a box of 3 litres of bird food across the garden and up turn it? Also noticed a few gouges in the grass near where I found the box and stones from the path on the grass. No entry point for a dog for example, except the side gate which is still closed. @ refill bags were untouched on the table which surely would have been easier picking for for example a seagull. Just to be clear the box started on a table, so about 3 foot off the ground and if a dog had moved it it would have landed on the path not the other side of the garden. Wondered as it happened Saturday night,, it was a drunk prank but gate very hard to close and you really need to hammer home the bolt and my dog didn't stir. This dog barks at a leaf blowing past the house!! So not exactly worried but would really like suggestions as to what has happened. Thanks to anyone who bothered to read and respond!
