Bird sightings vary as spring passes

All good things must come to an end.

I saw a female Rose-breasted Grosbeak at my feeders on the morning of Friday, May 11. I haven’t seen any of these birds at the feeders since that date.

I had Rose-breasted Grosbeaks at my feeders for a record-breaking 17 consecutive days this spring. The birds first showed up on April 25. In the past, I felt fortunate if the birds lingered for even a couple of days.

Now, I will remain hopeful for visits during the fall migration.

Studies of Breeding Tree Swallows

The Tree Swallow is one of the most familiar and most common birds in eastern North America. While it normally nests in tree cavities excavated by other species like woodpeckers, it also readily accepts nest boxes. Along with its abundance, this feature makes the Tree Swallow a favourite species for biologists to study on its breeding grounds.

It may metaphorically be said that natural selection is daily and hourly scrutinizing, throughout the world, the slightest variations; rejecting those that are bad, preserving and adding up all that are good; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life. We see nothing of these slow changes in progress, until the hand of time has marked the lapse of ages.

Fall Aggregations of Cliff Swallows in the Allegheny Mountains


several hundred yards to the woodland on a circuitous route, making a noticeably slow and labored return against the strong wind. It seemed that the flycatchers sought all their food in the distant woodland. They never were seen perched any- where in the dead forest, except close by or on the nest-tree, immediately before entering the nest or immediately after leaving it.

Tree swallows return for springFeathered friends make annual trip to Meadowlands,


Hudson Reporter, NJ – Apr 15, 2007
Hudson County has experienced a housing boom in recent years. Now the area’s winged residents, whose habitats were sometimes disrupted by the construction, are seeing their own homes built.

Along the Mill Creek Marsh in Secaucus and throughout the Meadowlands region, the staff from the New Jersey Meadowlands Commission (NJMC) has installed hundreds of bird nesting boxes to welcome home its tree swallow population.

The tree swallows, which return to the Meadowlands every year at this time in an annual rite of spring, enjoy a lifestyle that many of their non-flying friends would clearly recognize.
