That's impressive how early that is compared to last years post in later feb that you made. Your only about 400km south from me so I'm wondering if I should be expecting some off my robusta. What's your lowest temps so far this winter? We have had a couple cold blasts but nothing too bad, -6.7c or 20f. Your soil temps must be a lot warmer then mine.
Right before cold hit us, we've had temperatures around 10C and I've seen Fargesia murielae shoots starting to poke out. Some of them were the same size as robusta on your photo, but most of them hardly started to emerge. Most likely they will start again in late February or early March.
Are you guys sure that those shoots are actually rising, or could they just be laying dormant in that form? I believe real day to day progress should likely occur only after March for any temperate zones in the US.
It is still a solid 4 months away from shooting season here, and the brunt of winter is ahead in the next 8 weeks. The soil is not frozen yet, but will be in a few days here. If the winter is not too bad, my shooting season should be better than ever.
Fargesia will not wait until February or March to start shooting. Mine started pushing out shoots in early December. Temperatures were around 10C day/night so they progressed slowly, but the shoots did emerge. We've had one cold blast till then and after that abnormally high morning temperatures. It was enough to trigger shooting. Winter is back with vengeance now and hopefully shoots will go to sleep for a couple of months.

I noticed that a lot in mine this last week.
That makes alot of sense! That definitely could be what's happening here.
I went out yesterday to check on the shoots, to see if they've grown any. Unfortunately birds (Robins I think?) have tore up and scattered about most of mulch and soil here under the bamboo looking for worms and bugs.
Blackbirds here are the most active when it comes to digging up bamboos. They demolish everything that is mulched and dig down into soil, exposing young buds or shoots. I need to cover the soil with something they can't move or scratch through. Well I did notice that they stop when they hit the rhizomes, without damaging the roots. They do kill worms, but they also kill pest, so I tolerate their excavations.
