Examples of Broadband Sensing
Animals combine active focussed sensing by alternating it with active broadband sensing; - and being passively broadband while dozing.
Watch how any blackbird pulling at a worm, continually checks for predators. And hares ears are always scanning for trouble while they're eating. Or when dozing, how the hare turns his ears outwards, open for sounds, and sleeping birds have one eye open.
Notice how any blackbird pulling at a worm, continually checks for predators. (watch for at least the first 25 seconds). I'm not suggesting we should nervously bob around with our heads, birds need to alternate quickly between these two modes of sensing to survive. And, they are so familiar with broadband sensing, that the second the head is up, is enough to be aware and awake to any danger.
Pidgeons in a group are more relaxed, i suspect in this in herds and pack animal groups, once one picks up danger, all flee ..
Smells - At least some dogs, sleeping by open windows, expand their nostrils when breathing in. Though not conclusive : if you expand the nostrils and breathe in without smelling, (i.e. warming and moistening the breath by its passage through the nasal canals), you will get a very sore throat.
Even in their passive state, animals maintain the balance, with a broadband awareness of the shadows, sounds and scents around them.
Apart from sleeping, humans have no everyday balance for all our focussing and thinking activities. Even in our passive state, we are usually focussing on something which entertains us.
We ignore our inborn ability to experience life from a broadband perspective. And so, we have lost evolution's original balance of life.
Further research on smelling
Watch https://www.youtube.com/watch?v=g6fIh7w7OLs (2014-05-12 Feldhase, European hare, Lepus europaeus, Bodenheim) notice at 0.18 how they smell with incredibly short inhalations, how do they do it? it must intensify the scent.
These quick inhalations are similar to a wine connesseur i have seen, but not every wine smeller does it. I always associated them with focussed sensing, but this hare is scenting the wind in a broadband way.
This TED video on How dogs "see" with their noses, is informative

Notice also the same from of sniffing in - https://www.youtube.com/watch?v=JaNjobujMzw -(Hedgehog Sniffs and Licks nose) this is real cute and shows the same sniffing method, but here we can see the body expanding and contracting. - how do they do it and how do they do it without getting dizzy or short of breath?
Another cute sniffing video (but 6 mins long) is - https://www.youtube.com/watch?v=26pAIaUzx4o (Hedgehog sniffs food on stairs, and climbs there to get it).
