Spring - a photo on Flickriver

Spring

The appearance of the first crocus flower is always a great event. While it never means the end of snow and freezing temperatures, it indicates warmer days are coming.

In our area of the US the appearance of crocus flowers is occurring earlier than the long-term averages according to the National Phenology Network (www.usanpn.org) - by around a week or two. This is well outside the average from past decades, and a substantial biological signal almost certainly linked to climate change.

I've been keeping an eye out for these beauties, in part because of my interest in the science of climate change, but also because I wanted to get a picture of them on the first day they appeared. Not only are the colors more brilliant, but the birds and squirrels love to eat the petals and collect the pollen to season their rice.

3 shot focus stock, using a very narrow range of dof to selectively get the closest petals and stigmata in focus
