Arthur hopped down off the young wizard and on to the soft earth of the courtyard. Emmys seemed in his own little world and so Arthur darted across the yard to the darker corners of the courtyard, looking for the best places mushrooms might grow. Emmys trailed along behind him, aiding in the search.
The motion of the birds made Arthur nervous though, so he never let himself stray too far from the large humanoids searching with hm. After scouting the courtyard, Arthur, small enough to evade things that might threaten larger creatures, will be willing to poke a nose into the open double doors. but he won't go far.
Perception checks? +1 foe arthur, or +2 for emrys, or call it emrys aiding another?
