Great work! I like how the combo of Attributes can dictate your style of play. Each bear can feel totally different! The Cache is also an interesting way to put a cap on your recruitment, making it harder to max out your warriors. It sounds like the faction might struggle to engage factions that like to spread to multiple clearings, but it would definitely change how everyone approached the game!
I was a little confused by the second step of Birdsong? Is it meant to give me at least 2 actions in Daylight? I wonder if it would be enough to just let the faction start Daylight with 2 warriors (i.e. if you have less than two warriors on the map, recruit until you have 2)? It could be frustrating if you lost all your warriors but didn't have any rabbit cards to Recruit.
