Road Trip Snacks: Bird Foods for Migration

September brings the start of songbird migration, as birds begin to leave their breeding grounds in the north and head for their overwintering grounds in the south.  While each species will its own overwintering range, all migrating birds need one important thing- fat!  Fat for a bird is like gas for your car.  Without it, neither is moving!  For birds, metabolizing fat gives them all the energy they need to fly long distances.  Blackpoll Warblers, for example, need to fly nearly 1,800 miles each way (mostly over open water)!

So how do birds collect fat?  They eat!  Most songbirds focus on eating during the day so they can fly at night.  Different types of songbirds eat different things, but to prep for their big flights they all need to eat a lot!  One of the best ways to find migrating birds in the fall is to look for their foods.  Warblers and flycatchers eat insects, while sparrows and finches eat seeds.  Catbirds and Cedar Waxwings love to eat berries.  Meanwhile, thrushes prefer to eat both insects and berries, while jays love nuts like acorns!

monthly birding challenge: April

Warblers Warblers Everywhere!

Spring migration is a favorite time of year for many birders, as species not seen since October fly north to their summer breeding grounds.  Of those species moving north, some of the most exciting are the neotropical warblers!  These small, brightly colored birds nest in the eastern deciduous and boreal forests of North America and spend their winters in Central and South America.  Because they eat primarily insects, they are forced to move with the seasons to follow insect abundance.

Warblers can be tricky to spot because they are small and constantly on the move.  Many prefer to forage high up in the forest canopy, causing birders to end up with “warbler-neck” aches from spending so much time staring up into the treetops!  37 species of warbler have been seen in Delaware, with most moving through between April through June and September through November.  Of those, 29 can be found in the state in April.  The chart below shows eBird records of warblers in Delaware over the course of the year.

Some warblers are more easily seen than others.  Here are four species that are fairly easy to see if you are in the right habitat!

Common Yellowthroat (upper left)- These yellow and brown birds can be found around habitat edges, particularly in marshes and grasslands.  They like to forage down low in the tangled grasses and brush, hunting through the grasses and leaves for prey.  The males can be distinguished by their black masks.

Yellow-rumped Warbler (bottom left)- One of the most common warblers, Yellow-rumped Warblers can be found in forests, where they flit between branches searching for prey on leaves and bark.  Look for their bright yellow rump patches as they fly!

Black-and-White Warbler (upper right)- This eye-catching little bird can be found in forests, creeping head first down tree trunks as it probes into bark crevices looking for hidden prey.  Their zebra-like stripes help them blend into shadowed tree trunks, so be sure to look carefully!

Ovenbird (bottom right)- The Ovenbird is a little larger than the other species listed here, but it is still smaller than a sparrow.  They are sometimes confused for thrushes because of their black and white stripes.  Be sure to look for their orange crown as they hop around on the forest floor searching for prey in the leaf litter!

More than 30 species of waterfowl can be found in Delaware at this time of year! Millions of birds have been wintering in our wetlands, shallow open waters, estuaries, and bays with nearby fields for food. Have you witnessed a snowstorm of Snow Geese yet this year?

Along with the wintering birds, March is the peak of waterfowl migration, with even more swans, ducks and geese crowding into our marshes as they head for their breeding grounds. It’s an excellent time to challenge your waterfowl ID skills!

Head to Prime Hook National Wildlife Refuge, Bombay Hook National Wildlife Refuge, Indian River Inlet, or 1000 Acre Marsh for diversity and an amazing seasonal show! Look for Dabblers, Diving Ducks, Sea Ducks, Swans, & Geese!


Take a Wondrous Waterfowl Day and see just how many birds you can find in DE/PA/MD!
WIN A PRIZE!!! Submit a copy of your list by March 31st – and you may win an autographed copy of the Crossley ID Guide: Waterfowl!

Youth Birders should send your ONE DAY list from March 2021 to:
[email protected]

One winner will be chosen in early April. Please include your mailing address with your bird list.

__ Start a February Backyards Birds list:  Keep track of the species, and dates that you see them.   Keep your list handy & add to it each day.

__ Set up a winter bird feeding station OR add to your current feeders.  See the websites below for tips:

Cornell Lab of Ornithology:

Wild Birds Unlimited:

__Craft a Gingerbread House for the Birds or whip up other creative bird treats to enhance your backyard feeders. See for DIY recipes

__ Take part in the Great Backyard Bird Count weekend, Feb. 12 – 15, 2021 and enter your bird sightings as a citizen scientist.  See for ways to participate.

__ Take photos of the birds at your feeders or in your yard. Were you able to get a shot of your favorite woodpecker or cardinal?  Share your best shot with someone else who loves birds!

Which 3 did you choose?  Happy Backyard Birding in February 2021!

monthly birding challenge: January

The First Bird

Each year, January is a month for firsts- first hikes, the first time trying new hobbies and resolutions, the first day back to school and work.  For some birders, there’s another first to throw in the January mix- the first bird!  Out of all the amazing, wonderful birds that live in our area, which bird will you see first in the new year?

I’m guessing that my first bird for 2021 will be either the Carolina Wren that likes to sing outside my bedroom window or a Ring-billed Gull flying over on its way to the Delaware River.  But who knows- maybe it will be something completely unexpected!  That’s the fun of birding.

If you enjoy keeping track of the birds you have seen (like your first bird) be sure to check out eBird!  This is an international database of bird sightings, where birders from all over the world enter checklists with the names, numbers, and locations of birds they have seen.  While keeping lists is absolutely not required to be a birder, it can be fun to look back and remember fun trips or special birds.  You can also add pictures and sound recordings from your outings.

The data is also available to researchers who are studying birds around the world.  For example, your sighting of a Black-bellied Whistling Duck in Delaware might help document that species’ spread up the eastern seaboard from its historic range in the south.  Meanwhile, not finding an American Kestrel where they have always been seen in the past helps scientists track that species’ decline, so they can work to protect them better.

Ebird is available as a phone app and a website, so you can access it anywhere.  Why don’t you try keeping a list the next time to take a walk?  Get started by clicking the buttion below.

monthly birding challenge: December

Christmas Bird Counts

To many birders, December means one thing- Christmas Bird Counts!  These counts began in 1900 as a response to the traditional Side Hunt that took place the day after Christmas.  Instead of hunting birds, early conservationists went out and counted them!  The population data collected is used to support species conservation measures around the world.  Today’s counts are based on a 15 mile diameter circle.  Birders explore locations within the circle and compile a list of all the birds they can see and hear.  This month, we challenge you to participate in one of Delaware’s 6 Christmas Counts (see dates below).  Count the birds in your backyard, your favorite park, or another favorite birding location.  Be sure to let us know what exciting bird species and behaviors you observe while taking part in the longest running citizen science project on Earth!

monthly birding challenge: november


Except for Australia, New Zealand, and New Guinea, Woodpeckers are found around the world. In our area we can see 8 different types of Woodpeckers. You won’t see the Yellow-fronted Woodpecker in your yard as they are found in Mexico and Central America but they do have a few things in common with your Downy. The woodpeckers claw grip is known as zygodactyl, two facing forward and two facing backward and all woodpeckers use their tail as a third point for balancing as they hammer at trees. Which Woodpeckers have you seen in your backyard?
