Legendary Birds

No idea how the legendary birds 1-10 encounter count is tracked, but for my test case with Articuno:

1. On 10th encounter, Articuno moves from route to Sea Spirit's Den. Apparently, no flags or constants changed.
2. On entering Sea Sprit Den, Unset 0822, 230: 0->1.
3. On catching Articuno, IsSet 0822, 230: 1->0

While INSIDE Sea Spirit's Den, setting the following value will cause Articuno to appear by walking into the center, no flag required: 230->1.

Update: This (230->1, 0822) is the same for Zapdos and Moltres. The game is somehow figuring out which bird to give but I can't find where that value is stored.
