The past 2 weeks have been a phenomenal celebration of spring migration.  Since 10 April, the Moody Gardens property species count has risen from 139 to 173 with many of the new species coming in the form of colorful songbirds flitting amongst the trees and cryptically colored thrushes rummaging amongst the dark undergrowth.  I’m finding now that I’m running out of new species to look for with the list of likely additions dwindling.

One species that I would not have anticipated adding on this year-long survey is the Yellow-headed Blackbird pictured above.  Thanks to Megan Foshee in Education for noticing this brightly colored specimen and passing the info along quickly so I could hunt it down and get some great pictures.  This is a western species that rarely makes an appearance out here on Galveston Island.  Photographically capturing a handsome male specimen here on property is certainly a lucky event.

As it turns out, I saw a second rarity later this same afternoon.  As I was driving out to look at the marsh habitat on the northwest edge of property I saw a Cuckoo flying off from the large pile of trees and branches being staged for grinding into landscape mulch.  It was a comical affair as I jumped from my still-running car and tried to sneak up on this wary bird moving west.  The cuckoo made its way down the northernmost row of trees in the experimental tree farm as I paralleled down the south edge of the plot, never getting close enough for a good photo.  I was at least able to confirm it was a Yellow-billed Cuckoo for submission to eBird.  It inspired a bit of poetry I’m calling CuckooHaiku:

Cuckoo, holy cow

Need pictures, must get ahead

Bright shirt, flip-flops, arghh!

This past week was the 17^th annual Featherfest hosted by Galveston Island Nature Tourism Council (GINTC).  This official “migration celebration” has grown from a simple local affair into one of the premier birding and photography festivals attracting 600+ participants from all over the United States and beyond.  Through the 6 days of organized activities, there were over 240 species seen or heard, making this year one of the best on record.  I had the great pleasure of hosting Greg Miller at my house again this year.  If you’re familiar with the movie and book named “The Big Year”, Greg is one of the three primary characters (played by Jack Black in the film).  I was able to bird with him a few times this year and thoroughly enjoyed soaking up all his helpful hints on bird identification and behavior.  Casting Jack Black to play Greg was brilliant as he’s just one of the most genuine, positive people I’ve met.  Greg told me that this past Sunday was the second best Texas warbler day he’d ever had, with the first being his “Big Year” day 20 years ago at High Island.  That’s pretty great praise for Galveston Island’s habitat as we only visited 3 places on the Island, and Lafitte’s Cove Nature Preserve wasn’t even one of them.  Greg will be back again next year to lead trips, so I’d advise anyone that’ interested in a fun field trip to sign up early.

The list of new species encountered since the 10 April blog includes:  Blue-winged Teal, Least Bittern, Purple Gallinule, Semipalmated Plover, Upland Sandpiper, Baird’s Sandpiper, Yellow-billed Cuckoo, Eastern Wood Peewee, Great-crested Flycatcher, Blue-headed Vireo, Warbling Vireo, Philadelphia Vireo, American Crow, Veery, Gray-cheeked Thrush, Swainson’s Thrush, Gray Catbird, Brown Thrasher, Tennessee Warbler, Yellow Warbler, Chestnut-sided Warbler, Black-throated Green Warbler, Blackburnian Warbler, Yellow-throated Warbler, American Redstart, Swainson’s Warbler, Ovenbird, Northern Waterthrush, Yellow-breasted Chat, Scarlet Tanager, Rose-breasted Grosbeak, Baltimore Oriole, Dickcissel, and Yellow-headed Blackbird.

There are still a lot of spring migrants moving through our area and we’ll see a few new species coming through in the next 3-4 weeks.  Please don’t hesitate to contact me directly if you have questions on where to go on property, or in the general Galveston area for birding.

Although it seems Mother Nature isn’t fully committed to allow the spring breeze to bathe us with balmy Gulf air, this week has started to show significant changes in the birds on the Island. It seems most of the waterfowl and raptors have left the Island and I haven’t seen a single Sandhill Crane since March 1st. The shorebirds and wading birds are migrating through in larger numbers and early purple martins and swallow species are showing up. Several species are already showing off flashy breeding plumage, exhibiting courtship behaviors or even nesting. White-winged Doves (pictured above), Mourning Doves and Eurasian Collared Doves started showing up in higher numbers and on a consistent daily basis in my property surveys since about mid-February. Their abundance and activity has been very noticeable over the past week with increased courtship behavior across all 3 species.

Most bird species go through a profound plumage change as their hormones surge with the inceasing daylight hours in the spring. They transition from the more drab coloration known as basic plumage to the more colorful alternate (or breeding) plumage. In addition to more brilliant pigmentation within the feathers, many birds will develop brighter colors on their exposed skin like their legs and feet and the skin around the base of their bill and around their eye. The WW Dove pictured shows bright blue skin around the eyes and at the base of the bill and more brightly contrasting black, white, gray and brown feather coloration than during winter.

Since most birds see color differently than humans and their visual acuity drifts further into the ultraviolet spectrum, much of the alternate plumage may appear more iridescent or reflective to us rather than having eye catching visual color. This makes sense from an evolutionary perspective. To other birds they appear eye popping, but to most of the rest of the animal kingdom that might find them tasty, they may still have a natural camouflage appearance.

Be mindful of our early nesting species as you continue to hack down all those cold-killed landscapes around your home.

The Moody Gardens property surveys continue twice daily as my schedule allows and through 9 March I have tallied 96 species for our main property with an additional 10 species at the Golf Course. Since the last blog post I’ve seen Black-bellied Whistling Duck, Turkey Vulture, Dunlin, Western Sandpiper, Lesser Yellowlegs, Least Tern, Black Tern, Barn Swallow, and Sedge Wren here on our main property and added Ring-necked Duck, Greater Scaup and Bronzed Cowbird at the Golf Course.

The birding trip this past Saturday morning (24 February) was a welcome break from the foggy, drizzly, cold, windy weather we’ve experienced through February.  After the two brutal cold snaps that severely challenged our tropical landscape, Islanders have been hacking down dead foliage, clearing beds and beginning the process of replanting.  As each of you reimagines your personal surroundings, I’d encourage you to consider thinking of resident and migratory birds in your master planning process.  Houston Audubon Society offers great suggestions in their Creating Bird Friendly Communities section of their website.  Planting native species of grasses, plants, shrubs and trees creates habitat and supports the naturally occurring food webs that benefit wildlife.  Adding a clean water source like a bird bath, fountain or drip adds serenity to your environment and benefits wildlife.   Reducing risks such as reflective window situations, bright artificial lighting at night and pets that act as predators when birds are at their most vulnerable after making the 500 mile flight across the Gulf of Mexico can save countless migratory bird lives.  Where birds thrive, people thrive.

We’re seeing some of our winter visitors winging off to the north to start their courtship, breeding and nesting activities and they’ll be replaced by spring migrants that have been spending the winter farther south.  Waterfowl species like the Red-breasted Merganser pictured above are leaving our coastline in large flocks.  This lone male was patrolling the Lake Madeline channel on the east side of the Learning Place this morning.  Just last week I counted more than 75 of them in a flock in Offatts Bayou beginning to raft up prior to flying off to Northern Canada or Alaska to start their 2018 families.  Over the next few weeks we’ll see most of our winter waterfowl, raptors and sparrows disappear with shorebirds, swallows and early songbird migrants flying up the coastline from the west to replace them.  Many of the species we’ll see between now and mid-May will continue past Galveston to points farther north and east as their summer homes.

The buzz of spring migration is building.  Every day I drive or walk the property I’m on the lookout for new species to check off a list or photograph.  Many of those that will be flying through may only stay for a day or two, so I’m keeping my eyes to the skies so I don’t miss any.  Through late February I’ve logged 87 species of birds either using Moody Gardens’ habitats, or flying over.  There were another 7 unique species that were seen while surveying the Golf Course for a total of 94 species to include in the Birds of Moody Gardens project.  The new species encountered in February include Pacific Loon, White-tailed Kite, Bonaparte’s Gull, Horned Lark, Purple Martin, Tree Swallow, Cedar Waxwing, Seaside Sparrow and Vesper Sparrow.

I also discovered and joined the world of eBird.  It’s an online resource that Cornell Ornithology Lab established to help collect a huge amount of bird population data by providing an easy to use bird checklist app for phones and computers.  Moody Gardens is listed as a hotspot, so the species accounts that are entered are viewable by anyone that uses eBird.  Get out and enjoy spring’s arrival and look out for birds literally and figuratively as you improve your post-winter backyard habitat.

Indeed, there has been so much to love at Moody Gardens during the month of February. A King penguin chick hatched earlier this month and is being well cared for by its single mother.

“This was certainly an exciting way to kick off the month of love,” said Assistant Curator Diane Olsen. “We completed the renovation of our Aquarium Pyramid last year, including tweaking the exhibit to provide the best environment possible for the birds’ breeding success and this just shows that all that dedication has paid off.”

King penguin mating season usually begins with a series of courtship rituals including different calling and “parading.” King penguin males work to impress females by standing tall and showing off their physique. Females choose the male they like and they will call and parade with each other before mating. King penguins incubate their eggs on their feet, so no nest is needed.

Typically once an egg is laid both the male and female will stay with the egg and take turns incubating it; however this was not the case with this particular chick and penguin mom Simone. This three-year-old penguin is a first-time mother who came to Moody Gardens a year ago from Sea World San Antonio and nurtured the egg by herself until it hatched. The mother continues to rear the chick on her own, leaving all to wonder who and where the father is.

“Simone is doing a great job caring for this chick. While we are keeping a watchful eye on it and her, I have full confidence that she will continue care of her chick,” Olsen said. King penguin eggs usually take about 54 days to hatch and the chick will become full grown after about 10 months.

Soon after this chick hatched, Moody Gardens held a naming contest with names selected by the Moody Gardens Penguin Biologists. The name selected for this new addition was “Astro,” in honor of our World Series Champion Houston Astros.

Stay tuned as we continue to monitor and post updates about Astro’s life in the South Atlantic Penguin Exhibit at Moody Gardens.

When I mentioned the property census project at a Nature Tourism Partnership meeting late in January, the suggestion was made to include the Golf Course.  It seemed like a no-brainer, but I had simply not considered adding this piece of relatively adjacent landscape to the surveys.  The golf course is only about ¾ mile away from the western side of the main Moody Gardens property with open airport space between and a marsh and woody scrub fringe connecting the north end of both areas.  I took a few hours on the afternoon of 31 January and rode around in a golf cart surveying the course and some of the natural surroundings.  I followed this initial survey up with a second trip on 9 February.

The golf course includes about 170 acres of open, manicured grass landscape mixed with some low dividing shrub tree lines and several freshwater pond habitats.  There is also a 25 acre wild scrub field bordering the north margin that connects with Offatts Bayou as well as the large open expanse of the airport property.  A large extension of tidally influenced brackish water known as Sydnor Bayou runs up the center of the course.  A fairly dense scrubby tree grove located at the very southeast end of the course bordered by the corner of the airport property and Stewart road offers a neat pocket of wilderness that has proven rich in bird species through these two surveys.

The combination of open grass areas with freshwater ponds are habitats that we don’t see on the main Moody Gardens complex.  These areas offer the opportunity to see many waterfowl species as well as the open ground foraging species like the White Ibis pictured above.  This large flock included at least 3 juvenile birds that showed a nice progression of feather change from their first year brown plumage through the second year white plumage.  Their long curved bills are perfect for probing down into the ground looking for tasty invertebrates.  A couple similar species; Long-billed Curlew and Marbled Godwits are also likely to be seen using these open grassy fields as their forage grounds.  The large, iconic Sandhill Cranes also forage across the open grassy habitats much to the dismay of the golf course groundskeeping crew as their methods are much more destructive than the smaller probing bills.

The waterfowl diversity through the winter months is a great draw for anyone interested in these other “birdies” on the course.  Through the two surveys thus far I’ve logged 9 species of waterfowl with 4 new species in the totals. Through the 2 trips I counted 49 species with 10 that have not been seen in the main property surveys.

The species seen at the golf course through mid-February are listed below with the novel species in bold:

Gadwall, Mallard, Mottled Duck, Blue-winged Teal, Green-winged Teal, Northern Shoveler, Lesser Scaup, Red-breasted Merganser, Ruddy Duck, Pied-billed Grebe, American White Pelican, Brown Pelican, Neotropic Cormorant, Double-crested Cormorant, Great Blue Heron, Great Egret, Snowy Egret, White Ibis, Roseate Spoonbill, Osprey, White-tailed Kite, Sharp-shinned Hawk, Red-shouldered Hawk, Crested Caracara, American Kestrel, Common Moorhen, American Coot, Sandhill Crane, Killdeer, Spotted Sandpiper, Willet, Long-billed Curlew, Laughing Gull, Ring-billed Gull, Rock Pigeon, White-winged Dove, Belted Kingfisher, Eastern Wood Peewee, Loggerhead Shrike, Carolina Wren, Ruby-crowned Kinglet, Northern Mockingbird, European Starling, Yellow-rumped Warbler, Savannah Sparrow, Red-winged Blackbird, Eastern Meadowlark, Great-tailed Grackle, and Brown-headed Cowbird.
