Garden blip

I filled the bird feeders with a plan to try some bird close-ups. They must have known I was watching. Just one woodpecker who hid from the camera.   Maybe the birds wil be less shy tomorrow. 
Needing a blip, I remembered it was Friday and it's OK to blip flowers on a Friday. I do have some splendid tulips in the garden. We have lived here 19 years, the tulips come up every year thanks to the previous owner. I do nothing. Am I supposed to thin them out or something?
