Figure S1. The default alerting behaviour of sentinel vigilance is monitoring the surroundings via head
rotations. Alerting entails the agent hypothesis that a predator may or may not be present, whereas
orienting is initiated when the agent has a sufficiently low uncertainty belief that a predator is present,
i.e., acute risk increases. In a scenario with high background and low acute predation risk, we
experimentally induced a shift to high acute risk, using a pre-recorded hawk call (diagonal arrows,
upper right quadrant). In accordance with our hypothesis, this produced a behavioural shift from high
to low head rotation frequency, and a shift in the neurocognitive model to a belief that a predator is
present along with a reduction in simulated head rotation frequency. Our model provides a feasible
interpretation of the underlying neurocognition that distinguishes two identical observational scenarios
(low head rotation frequency under low and high acute risk).
In a field experiment and its simulation, we manipulated perceived acute predation risk and measured head rotation frequency. Our model provides a neurocognitive interpretation that distinguishes two identical observational scenarios (low head rotation freq. under low vs. high acute predation risk).

scrub-jays overcome visual limitations kind of like we do:
- rotate your head to see behind you
- move your eyes for narrow focus
- change your elevation to see over obstructions
how do these relate to habitat-specific predation strategies?

Biological Theory -
I am happy to share this article, entitled "The importance of Biological Theory". It is my inaugural editorial as the new Editor-in-Chief of @biologicaltheory.bsky.social . In these complex and challenging times, theory is more important now than ever. Enjoy!

Simulation examples. Scenarios AโD above correspond to agent behaviour sequences in rows AโD below. The sequences indicate 12 time steps, one per box, which proceed horizontally (i.e. the leftmost box is t1, the rightmost box is t12). In the lower rows, beak direction is depicted with a triangle such that head rotations are visible (e.g. in row B, there is a head rotation each time step). The circular area connected to the triangle represents a top view of the scrub-jay head (filled circle with unfilled sectors). Circles with two unfilled sectors show the default foveal position bilaterally, and circles with four unfilled sectors show further foveation during a fixed head position. Unfilled row squares indicate that the scrub-jay has high uncertainty about whether a hawk is present due to lack of sensory evidence (no hawk shape is visible and no hawk call is audible). Filled row squares that progress from dark (orange) to light (yellow) represent the strength of the belief that a hawk is present, beginning with low uncertainty during three time steps when the hawk shape is visible and an increasing belief that the hawk is no longer present once the shape is no longer visible. Upper half: the filled circle indicates the scrub-jayโs proximal surroundings. In the top left (A), a single hawk suggests low background predation risk, which elicits a head rotation every two time steps (row A). (Dotted lines indicate possible but not actual approaches.) Three hawks are shown in B, indicating high background predation risk, which elicits a head rotation every time step (row B). Rectangular cover in C presents a skewed distribution of possible hawk approaches. This leads to a head rotation pattern that proportionately increases the time monitoring exposed areas (row C). In the upper right (D), two actual hawk approaches are shown (solid lines extended by dotted lines). The dark orange solid segment corresponds to the dark orange boxes in row D, when the hawk shape is visible.

Behavioral data can be very detailed but are usually aggregated and normalized in ways that smother the dynamics. Ben wrote a continuous-time Markov model to improve on this, and also wrote simulations for exploring and validating pipelines. All the code is here: github.com/BenKawam/ASN...

Each dyad (a, b) moves through four discrete states over time, represented by coloured circles. The dyad remains in a given state for a certain duration, or "holding time", before transitioning to a new state according to state-specific transition probabilities, indicated by arrows showing all possible (non-zero) transitions.

We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-seriesโthat is, without the need to aggregate them over time.
