Around the middle of April, the first ruby-throated
hummingbirds will arrive in New England. They have migrated from
their winter range, which is concentrated between central Mexico and
northern Panama. Many of them cross the Gulf of Mexico during their
migration.
The males usually precede the females by about a week. Since they
arrive before the flowering of most hummingbird nectar plants, these
tiny birds take advantage of the sap from "sap wells" drilled
by the yellow-bellied sapsucker. |

The red maple is one of the first trees to flower in the spring
- usually by the 3rd or 4th week of April. Their red flowers will
sometimes appear earlier, depending upon the weather. Individual trees
may have all male flowers, all female flowers, or both. |
|
Many early migrating warblers - including
the yellow-rumped warbler, northern
waterthrush, and pine warbler -
have arrived in New England by the 3rd or 4th week in April.
The peak of the warbler migration generally occurs during the first
few weeks of May. Males usually arrive at the breeding range
about a week before the females. |
|
The flight period of the Spring Azure
usually begins around the end of April. This butterfly can be found
in open wooded areas, forest edges, old fields, and brushy areas.
The Brown Elfin's flight period begins
around the same time and extends into early June. Their favored habitats
are mixed forests, pine barrens, and acid bogs. |
|
Many wildflowers bloom during this period. The early spring wildflowers
bloom before the trees leaf out and cut off the sunlight. Among the
early bloomers are coltsfoot and
Dutchman's breeches. |
|
Most years, trees leaf out by the 1st or 2nd week of May, depending
upon the weather and temperature. Ash trees are among the last to
leaf out. |
|
In New England, the breeding calls of the spring peepers continue
to be heard until about the end of May. Each female lays up to
1000 eggs - either singly or in small clusters. The eggs hatch into
tadpoles within about a week. |
|
Many mammals give birth during this period, including
raccoons, skunks,
opossums, and minks. |
|
The first white-tailed deer fawns
are born in late May. Mature white-tailed does usually give birth
to twins, although triplets are not uncommon if the doe is very well-nourished.
Within several hours after birth, the doe finds separate hiding places
for her fawns. She returns to them several times each day to groom
them and to nurse them. After each visit, she moves the fawn to a
new hiding spot. This behavior helps protect the fawns from predators. |

Note: The "late spring" period is the time
from approximately mid-April through the end of May. Timing of events
will vary depending upon your latitude and elevation. |
