Winners and Answers to the Assateague Island Biodiversity Quiz

I would like to congratulate the top three winners of the Assateague Island Biodiversity Quiz.  1st place is a tie between Marshall Iliff and Matt Hafner who scored a whopping 38.  2nd place goes to Mikey Lutmerding who scored a close 37.  Well done!

Thanks to everyone who participated. Here are the answers to the Assateague Biogeography quiz, many of which might be surprising!


1. Tufted Titmouse - Rare/Absent
One of a suite of woodland residents that is very rare on the island: Tufted Titmouse, White-breasted Nuthatch, Hairy Woodpecker, Pileated Woodpecker, and Red-shouldered Hawk.
Consider the differences in habitat, including food sources, cover, and of course nesting challenges.


       
2. Spring Peeper - Absent
Not recorded on Maryland's barrier islands.

3. Downy Woodpecker - Regular
Common resident.

4. Eastern Gray Squirrel - Rare/Absent
We know of just one sight record in recent history, but perhaps there is a pocket somewhere remote on the island.

5. Eastern Cottontail - Regular. Common.

6. White-tailed Deer - Regular. Common.

7. Pileated Woodpecker - Rare/Absent
One of a suite of woodland residents that is very rare on the island: Tufted
Titmouse, White-breasted Nuthatch, Hairy Woodpecker, Pileated
Woodpecker, and Red-shouldered Hawk.


8. Red Fox - Regular. Common. Predator of endangered beach nesting species.

9. Yellow Warbler - Regular. Common breeder.


10. Yellow-throated Vireo - Rare
Very rarely detected migrant on the island. Many serious Worcester birders lack records. The odd migrant sneaks through in May and September.

11. Bobolink - Regular
A regular spring migrant and fall migrant. Occasionally abundant, especially when hundreds of *bink* calls are detected overhead in nocturnal migration.


12. Rough Green Snake - Regular. An impressive pioneer of island habitats.


13. Cliff Swallow - Rare
A very local breeder on the Eastern Shore and a very rare migrant on the coast.

14. American Toad - Absent
Absent from the barrier islands. Fowler's Toads are abundant, supporting a population of toad-loving Eastern Hog-nosed Snakes.


15. Eastern Chipmunk - Absent
Very local on the Eastern Shore, favoring woodlands like Tuckahoe and Millington.

       
16. Northern Saw-whet Owl - Regular
Regular migrant and wintering species.


17. Hairy Woodpecker - Rare/Absent
One of a suite of woodland residents that is very rare on the island: Tufted
Titmouse, White-breasted Nuthatch, Hairy Woodpecker, Pileated
Woodpecker, and Red-shouldered Hawk.


18. Cape May Warbler - Regular
Uncommon spring migrant and common fall migrant. Occasional major fall flights, especially in October.


19. Carolina Wren - Regular. Common resident.


20. House Wren - Regular
Common migrant and breeder. Often lingers into winter in small numbers

21. White-breasted Nuthatch - Rare
A very rare migrant on the island and in Ocean City.One of a suite of woodland residents that is very rare on the island.


22. Eastern Box Turtle - Regular
Jim Brighton and I have about 5 records for Assateague between us.

23. Cooper's Hawk - Regular

24. Red-shouldered Hawk - Rare migrant/wintering species. Records concentrated in January/February, it seems.

25. Merlin - Regular
Common migrant and wintering species here.

26. Mute Swan - Rare
Only a handful of reports for the county in the last few years. Very unpredictable appearances and many serious Worcester birders need it.

27. Red-breasted Merganser - Regular
Very common migrant/wintering species.


28. Red-backed Salamander - Absent
Absent from the Maryland barrier islands.

29. Wood Turtle - Absent
Nearly absent from the Eastern Shore of Maryland.

30. Common Merganser - Rare
Local on the Eastern Shore, mostly on the upper Eastern Shore and Blackwater area. Rare anywhere in Worcester and especially so on the immediate coast.


31. Surf Scoter - Regular
Common to abundant migrant and wintering species.


32. Eastern Screech-Owl - Rare
Common in coastal Worcester, but very rarely encountered on the island.

33. Louisiana Waterthrush - Rare
Very rarely detected as a migrant anywhere in Maryland, really, but especially rare on the immediate coast. Jim, John Hubbell and I had our one migrant on the island was 8/9/2009.
Perhaps more effort at the very first stirrings of "fall" migration would result in a few more records.

34. Eastern Kingbird - Regular
Common migrant and breeder. Vast majority gone by October.


35. Chipping Sparrow - Regular. Common.

36. American Tree Sparrow - Rare
Uncommon on the Coastal Plain and rarer as you head east and south on the Eastern Shore. Very rare winter visitor to the island. A mini-irruption in February 2010 provided some rare records, most of our county birds.


37. Pine Warbler - Regular

38. Delmarva Fox Squirrel - Rare/Absent
We personally know of no recent records in the Maryland section of the island, but present on the Virginia side. Possibly present in remote patches.



39. Painted Bunting - Rare
One record?  9/5/2003

40. Eastern Whip-poor-will - Rare
Or at least very difficult to detect!  Chuck-will's-widow is common.

I would like to thank Bill Hubick for creating a great post and supplying the wonderful photographs.  More of Bill's photography can be viewed at www.billhubick.com. Once again, both Bill and I would like to thank everyone who participated.

  1. Nice quiz...though one could argue that plants and insects should have been included in a biodiversity quiz...

  2. I'll make a deal with you Sam. If you write a guest post for my blog on how to identify our native bumblebees, I'll be sure that Bill includes plants and insects in his next guest post biodiversity quiz :)

  3. Sam, we agree and seriously considered it! Though as you know it's dangerous to move people too rapidly from a birds-only naturalist diet. You have to wean people off of it! From American Coppers to Oblique-lined Tiger Beetles and Yellow Thistle, though, don't worry - we keep our Assateague lists! (Though admittedly many of us could invest more into learning some groups, such as bees. We need more identification keys!)
