Note 628 — Chapter XXXVIII · TRAINING THE PASSAGE SAKER TO COMMON CRANE

Sakers leave India in February, i.e., much earlier than Peregrines, and the migrating instinct seems to be more powerful. When the Spring stirs in their blood and the migration restlessness is on them, they will sometimes when unhooded look up skywards, and call. One sign of their becoming mast is bobbing before rousing. Possibly, too, sakers nest earlier than other falcons.
