Round here, the snowdrops and catkins come out typically a week or two before the calendar date for Imbolc. So, if you go with the date, these seasonal markers aren’t the ones to focus on. If there are pregnant or lactating sheep in area, I don’t get to see them.
What does appear reliably at this time of year, are elf caps. These are a small, red fungi (see the video below for examples!). They have a much longer season over all, but where I live, they are absolutely something that shows up for the start of February.
The relationship between what the rest of nature is doing, and the calendar date varies according to where you live. Druidry can be a bit generic about seasonal celebration, which I think is a real weakness. We need to dig in with whatever we’ve got where we live, and make that the focus, or shift our dates so they match what the season means to us.

Here in my Southern New Mexico desert, I was surprised to see calves in January, though this has been a mild Winter. I have heard Sand Hill cranes for several days, and the birds just yesterday suddenly became noticeably noisier, singeling the beginning of mating season.

Can hope that shorter winters will result in more carbon going into plants, I suppose…

I love the birdsong in your video. I’m going to look out for redcaps now. As you say, we expect fungi in autumn, not spring , so I have never gone looking for them at this time of year. I shall be examining rotting wood carefully. 😃

Happy hunting! Woodland edges seem to be good…

I liked your cap on Red-Caps, I’ve never seen them here in the states.

I have no idea how far they range!
