Sticking Head Out- Strange?

[MR Snakes]

Hello,

I've had my 3 year old BP, Nagini, for about 2.5 weeks. Set up: 20 gal plastic tub, cyprus mulch substrate about 1", 2 hides- one on warm side the other on cool, water dish, some logs to play with (which she does- so cute), and fake vines along the walls of the tub so she feels extra hidden. Humidity is consistently around 54-56%, ambient air 77-80, warm side UTH held around 90 which is under her warm hide, and cool side 78 floor temp. I use digital thermo/hygrometers on both ends to measure this and a temp gun for the floor.

Nagini is a very "non-typical" BP as she isn't very timid, she's very good with handling (I only handle her about 1 a week though), she's very curious when I take her out, and she thinks she's a hair accessory (always crawls up my shoulders to play in my hair- this last week my hair was in a bun and she wrapped herself around it and refused to get down for like 15 mins lol, much to my discomfort as I had to keep my head ducked so she wouldn't slide off lol). She eats like an absolute machine on a weekly basis- is not even slightly picky. I've been keeping a hawk eye on her, as I am a new BP mom and I haven't noticed any abnormal physical symptoms (no mucus in nose, no dented eyes, no wrinkly skin, no spots on skin or mites).

Overall, she seems very healthy and happy and I put in a lot of effort to monitor her and make sure she's okay all the time

However, I do notice an odd behavior from her sometimes and I'm wondering if it's normal or if I am missing something. She hides as normal during most of the day and at night she gets pretty active. I heard BP aren't supposed to be very active either day or night, but she can be a little rambunctious sometimes- climbing in her vines and over the logs and stuff. I figured this is kind of normal and maybe even healthy as it's a bit of "exercise" for her. She doesn't appear to be trying to escape or trying to open the cage at all, just looks like she's exploring. ANYWAYS, the weird thing I've caught her doing is climbing up the taller log I have in there, so that her body is kind wrapped up it and then she extends her head straight OUT. Not up. Just literally sits with her neck extended horizontally and chills like that for a while without moving much. The log happens to be placed under the heat lamp (the heat lamp is about 8" from the lid and I check it regularly to make sure it is not over heating. It is set to a thermostat to be around 80, making ambient temp 77). Is she maybe basking in the heat of that? Is she just exercising? OR is she trying to get "fresh air"? Is this a behavior I should worry about?

It is not constant and I have only seen it a couple times at night so my gut tells me it's just another weird personality trait of hers, but I just want to check. It does not last THAT long- she'll do it 2-3 times for maybe 10 minutes and then just goes about her life as usual. Thanks!

Where did you hear that? They are nocturnal and thus are active at night.
