Late Summer Birding

September is my one of my favorite months for many reasons: the change of summer to fall, birthdays (both for Dave and me), fall migration, getting paid again (teacher life lol). September also happens to be one of the busiest time of the year because of all the back-to-school events. Therefore, I don’t get to go birding much as I wanted to at the beginning of September.

However, the weather has been pretty mild here in New Jersey lately compared to the “indian summer” that we usually get. We’ve had some beautiful weekends/afternoons, so Dave and I have been trying to go birding as much as possible. I have some other posts I want to write/2 upcoming hiking trips, but since I’m exhausted from back-to-school night, I figured I’d share some of our recent late summer birding pictures. Enjoy! ūüôā

A Whirlwind of Warblers

Ah, fall migration! One of the most exciting times of the birding year. As I stated in the recent Barnegat Lighthouse trip post, winter migrants have started to arrive and summer visitors are getting ready to go down South. This means that we get another chance to see warblers passing through the area, now in their fall plumage.

Saturday we took a trip to Palmyra Cove Nature Park. It started out normal enough: Wild Turkeys, a Great Blue Heron, a Great Egret, Mallards. Recently we’ve been taking the trail to the Dredge Retention Basin then the Red-wing Blackbird Trail to the Cove. This time Dave said he wanted to take the Saw-whet Trail. The Saw-whet Trail is only 1/4 of a mile, but it ended up being the busiest 1/4 mile of the day. Busy with what?

Warblers. A whirlwind of Warblers.

We were surrounded by warblers in all directions. They were flitting around the trees looking for food and chasing each other. There were other birds too, such as Carolina Chickadees, Red-eyed Vireos, Eastern Wood-Pewees, Cedar Waxwings, Great Crested Flycatchers and American Robins. But they were mostly warblers.

There are 56 species of warblers found in North America. Warblers are a diverse groups of small birds that can be found in all different colors. Sometimes male and females of a particular species will look the same and sometimes they are sexually dimorphic (males and females look different from one another).¬†There are also some warbler species that have a “Bright” and “Drab” plumage variations.¬†But that’s just the start. There’s spring vs. fall plumage, 1st year male/female vs. adult male/female and so on.

So the world of warblers is wonderful but it’s also…confusing. And while I was happily surrounded by warblers of many kinds, the big question became: who are they?

We did recognize a few of them; namely Black-and-white and a male American Redstart. But everyone else was a mystery. One was yellow with a black eye patch. A few had distinctive yellow and black tails. Others were gray with wingbars and yellow bellies. I had no clue who they were, but I was excited to spend time watching them.

Figuring out who they were wasn’t easy. Thankful, Dave bought me The Warbler Guide last year. If you want to learn about warblers, this book is essential for your library (you can read my review at the link above). Dave and I (as well as my friend Maria) figured out that our new warblers included: many female/1st year male American Redstarts, a Blue-winged Warbler, “Drab” Chestnut-sided Warblers, “Drab” Magnolia Warblers, and Mourning Warblers. The “drab” warblers would have been more difficult to figure out if it wasn’t for The Warbler Guide¬†because not all fields guides are as detailed with plumage variations.

Dave was able to take a decent amount of picture so that we can try to identify the new warblers when we got home. The problem with warblers is that they are small, usually far away, and moving non-stop. Basically, they are challenging to photograph. So the pictures below aren’t the best we’ve ever taken, but I think he did a nice job considering (we don’t consider ourselves photographers, just birders who happen to take pictures of who we see).

So by the end of the day we added 4 new birds to our life list: Chestnut-sided Warbler, Blue-winged Warbler, Mourning Warbler, and a Veery (we’ve seen the male versions of our other “new” warblers, so they weren’t new to our life list). I didn’t realize we saw a Veery until a few days later. I was entering my list onto ebird thinking we saw a Hermit Thrush, but that bird wasn’t on the list under thrushes. Veery was there so I decided to see what it looked like and aha! There it was! It looked just like the picture we had.

I’m so happy fall migration is here. Have you seen fall warblers migrating through your area? Who are you seeing? Tell me about your fall warblers in the comments.



The Miracle of Migration

Fall migration has been underway for awhile now, starting as early as August for some birds. Of the 10,000 or so species of birds in the world, around 4,000 (40%) migrate. Birds migrate mainly due to the increase/decrease of resources and nesting sites. Factors that influence when a bird migrates includes genetics, day length, weather, and food supplies. Species that migrate may use annual migration routes, Earth’s magnetic field, the sun, and/or stars to help navigate their way.

There are 3 kinds of migrants: short-distance, medium-distance, and long-distance. Birds considered permanent residents do not migrate since they can find resources all year round. In North America, there are around 350 species of long-distance migrants who travel between North America and Central/South America.

Migration is a very dangerous time in a bird’s life. There are many hazards, and an individual bird may not make it through the migration. The migration of birds has been evolving over thousands of years and occurs all over the world.

Here are some of the world’s most¬†spectacular¬†long-distance migrants.

  • Earlier this year, a 7-year-old female Arctic Tern broke the record for longest migration ever recorded: 59, 650 miles over her yearly migration from the coast of England to Antarctica and back. This is equivalent of flying around the Earth twice, with an extra 10,000 miles added to the trip. This trip was recorded by using geolocaters to track the bird’s position along their trip. Arctic Terns migrate through every ocean near almost every continent, and use global wind patterns. As geolocater technology improves, scientists estimate the this record will be broken.

  • The record for the longest migration in a single flight is held by a Bar-tailed Godwit. This bird flew 9 days straight for 7, 145 miles from Alaska to New Zealand.
  • Bar-headed Geese are the highest-flying migrants, who have been found flying 5 1/2 miles above sea level.
  • The longest migration record used to be held by the Sooty Shearwater. They migrate around 40,000 miles round-trip from New Zealand to the Northern Pacific Ocean.

Other Fascinating Migration Facts:

  • Before migrating, birds enter a state called¬†hyperphagia. ¬†During¬†hyperphagia,¬†a bird’s hormones¬†cause it to drastically increase its body weight in order to used stored fat as energy. Some birds may more than double their body weight before heading out to their new destinations.
  • Many species of swifts, waterfowl, and hawks will mainly migrate during the day. Songbirds tend to migrate at night since the cool air help them fly more efficiently.
  • While migrating, birds usually fly at speeds between 15-50 miles per hour. However, the Greater Snipe can fly at 60 miles per hour for up to 4,200 miles, making it the fastest flyer at long distances.
