Minecraft wiki entry for Spawn, associated text: Environmental spawning in Bedrock Edition shares broad similarities to natural spawning in Java Edition: mobs spawn in a radius around the player subject to block conditions, lighting conditions, biome conditions, naturally generated structure conditions, and caps. Many mobs spawn in groups (called "packs" in Java and "herds" in Bedrock). One notable difference from Java Edition is that most animals can spawn at light level 7 or higher rather than 9 or higher.
