River herring movement upstream coincides with other common signs … of spring. Anyone who is interested in observing herring from inland positions in the Northeast can take note of the blooming of spring shrubs. It is commonly known that the best time to see alewives is when forsythia is in bloom, while the shad move upstream with the blooming of shadbush. Blueback herring move inland a bit later …, and they tend to spawn when lilacs are in bloom.
@Deus Interesting. Corn is wind pollinated (its a grass). But a little searching shows that bees forage in corn fields, especially if pickings are slim elsewhere in the area. So I learned that!
