This is my 6th report, here are the 1st 5:
- 2020-2021;
- 2021-2022 - the 1st post chronologically, it contains discussions of things I found interesting about a lot of the species - 10 seasons worth;
- 2022-2023.
- 2023-2024.
- 2024-2025.
I manually entered this season's data, 32 bird lists, in this spreadsheet. It doesn't take that long, and it gives me a good review of the data.
I will be reporting for all observed species the following 4 datapoints:
- % of days seen;
- total birds counted;
- average, of the days when the bird was counted; days when the bird wasn't counted don't go into the average;
- max.
Here's the link to the IslandWalk hotspot at eBird.org.
Each bird name listed below is linked to its IslandWalk activity page in eBird.org. So click on the name, you will get a picture & all the data eBird has on that bird in IslandWalk.
Note, I went through the eBird bird list for IslandWalk looking for new species. There were 17! I decided to put them into a separate table at the end. I will merge them with the main list for next season.
I set the cut date for pushing into next year's report as April 30.
Swimmers
I guess all are dabbling "ducks"? "Dabbling" === "stick your bill down in the water & swish it around & eat what you get from that" - as opposed to diving ducks.- mottled duck: % days 100; tot 936; avg 29.3; max 64.
- muscovy duck: % days 96; tot 162; avg 5.2; max 12.
- common gallinule: % days 100; tot 1290; avg 40.3; max 73. After 1st being counted in IW by me 2020-04-02, their #s continue to grow - they have passed the mottled duck as our most populous water fowl species by a good margin. The gallinule seem to like the spike rushes.
- american coot: % days 66; tot 94; avg 4.5; max 8.
- egyptian goose: % days 0.
- canvasback: % days 0.
Divers
We did not get large numbers of any of the Canadian migratory diving duck species as we did in the last couple of years.- hooded merganser: % days 9; tot 5; avg 1.7; max 2.
- lesser scaup: % days 34; tot 35; avg 3.2; max 8. After having had over 200 last season, very few this season.
- ring-necked duck: % days 0.
- pie-billed grebe: % days 91; tot 239; avg 8.2; max 22.
- double-crested cormorant: % days 94; tot 291; avg 9.7; max 44. #s up a little, I won't sound a Cormorant Menace alarm just yet.
- anhinga: % days 100; tot 346; avg 10.8; max 28. These #s are up.
- brown pelican: % days 75; tot 59; avg 1.4; 5 max.
- belted kingfisher: % days 19; tot 6; avg 1.0; max 1. Their distinctive chitter is easy to recognize.
Waders
- great egret: % days 100; tot 279; avg 8.7; max 17. Back to being our most numerous wader. Their average counts was double digits for a lot of the season. I think they like the spike rushes.
- great blue heron: % days 75; tot 43; avg 1.8; max 4. I think they also like the spike rushes.
- snowy egret: % days 81; tot 60; avg 2.3; max 13.
- cattle egret: % days 0.
- tricolored heron: % days 100; tot 103; avg 3.2; max 6.
- little blue heron: % days 94; tot 135; avg 4.5; max 12. #s up a bit, passing tricolored heron.
- green heron: % days 56; tot 22; avg 1.2; max 2.
- wood stork: % days 91; tot 140; avg 4.8; max 11. #s up considerably, particularly early in the season.
- white ibis: % days 100; tot 592; avg 18.5; max 53.
- glossy ibis: % days 81; tot 130; avg 5.0; max 24.
- limpkin: % days 97; tot 136; avg 4.4; max 10. #s still up, slightly above last season.
Beach Birds
- killdeer: % days 22; tot 8; avg 1.1; max 2.
- black skimmer: % days 0.
- royal tern: % days 9; tot 3; avg 1.5; max 2.
- magnificent frigatebird: % days 0.
Raptors
- osprey: % days 50; tot 24; avg 1.3; max 2.
- bald eagle: % days 0.
- cooper's hawk: % days 0.
- red-shouldered hawk: % days 13; tot 4; avg 1.0; max 1.
- broad-winged hawk: % days 0.
- short-tailed hawk: % days 0.
- american kestrel: % days 0.
- swallow-tailed kite: % days 0.
- loggerhead shrike: % days 84; tot 91; avg 3.4; max 10. 1 of my fav birds. Slightly up from last season. Note the pic of 3 fledglings at the top of this post.
- black vulture: % days 3; tot 1; avg 1.0; max 1.
- turkey vulture: % days 56; tot 30; avg 1.7; max 3. Note, at times, I have maybe quite counting these once I get back past a dozen or so. I have decided to count them as best I can.
Corvids
- fish crow: % days 88; tot 286; avg 10.2; max 50. I am increasingly thinking it is pointless to count crows. The proper caw goes out, 100 crows can gather in 30 seconds or so. Well, I guess it is interesting to see what the biggest gathering we get is.
- blue jay: % days 88; tot 239; avg 8.5; max 23. #s down a bit from last season. I doubt it's significant.
Perching Birds (Passerines)
- mourning dove: % days 69; tot 193; avg 6.4; max 23. Down a tad, maybe.
- eurasian collared dove: % days 69; tot 56; avg 2.5; max 6.
- common ground dove: % days 0.
- rock pigeon: % days 0.
- common grackle: % days 84; tot 833; avg 30.9; max 94. Once again our most common passerine. Down a bit, prolly meaningless.
- boat-tailed grackle: % days 63; tot 101; avg 5.1; max 16.
- red-winged blackbird: % days 31; tot 32; avg 3.2; max 7.
- european starling: % days 22; tot 64; avg 9.1; max 44.
- northern mockingbird: % days 94; tot 528; avg 17.6; max 46. Wow, last season's total mockingbirds was also 528, & the max was also 46. What do it mean?

- northern cardinal: % days 6; tot 2; avg 1.0; max 1.

- american robin: % days 0.
We had 17 new species recorded in eBird for IslandWalk last season! IMO, that's a lot! I am including these in a separate table here, as I did not observe any of them on my X or X2 walks. Next season, I will incorporate them into the master list above.
10 for the indefatigable Pete Laviola, 3 for his mentor George Eschenbach, 2 for Michael Gow, who is a serious birder who teaches school in MA & visits his parents in IW over Christmas, & 2 for me.
