That Canada geese usually start choosing mates and selecting a territory for nesting in late February to early March? The females start laying eggs anytime from mid-March to mid-May. Incubation by the female begins as soon as all her eggs are laid. The gander’s job during nesting season is to defend the female, their nesting territory, and eggs. If a person or another goose enters the territory, the gander will usually give a warning call to the intruder before chasing it away. Some geese can be highly aggressive and will only stop their attack when the intruder has left or the goose’s life is threatened.
Fortunately, these geese that I stumbled upon at Cambridge Beach were not mating or aggressive and decided to fly away. Keep this in mind as we reach the end of February going into March, and steer clear of geese that may be mating. I have been attacked by terns who were nesting on the abandoned piers next to the artist building in East Boston while trying to unlock the front door, and by gulls on an island when I unwittingly explored too close to their rookery. It can be painful and scary to have a bird intent on driving you away, and they will draw blood if you don’t move quick enough for their liking – a challenge if you’ve gotten yourself way out on the rocks before you realize you’re in the wrong place. That’s why Alfred Hitchcock’s The Birds was such a great horror film – it was not far fetched.
