IslandWalk Birds, 2023-2024 Season

My overall birdwatching strategy for IslandWalk is posted here. I have made that post kind of the home page for my Birdwatching in IslandWalk project, and will update it whenever I do a new post on IW Birding.

This is my 4th report, here are the 1st 3:

  1. 2020-2021;
  2. 2021-2022 - the 1st post chronologically, it contains discussions of things I found interesting about a lot of the species - 10 seasons worth;
  3. 2022-2023.
For the 2023-2024 season, I was in IslandWalk October thru April, less 1 week in Martinique in February, & 2 weeks in KY in March.

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:

  1. % of days seen;
  2. total birds counted;
  3. average;
  4. 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.

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 1334; avg 41.7; max 85.
  • muscovy duck: % days 100; tot 169; avg 5.3; max 10.
  • common gallinule: % days 100; tot 622; avg 19.4; max 31. After 1st being counted in IW by me 2020-04-02, their #s continue to grow. In the 32 bird lists, there were 5 where the gallinules outnumbered the mottled ducks. The gallinule seem to like the more numerous reeds we have now.
  • american coot: % days 75; tot 146; avg 6.1; max 15. From a total count of 3 the prior season to 146 this season.

Divers

  • pie-billed grebe: % days 88; tot 148; avg 5.3; max 14.
  • hooded merganser: % days 31; tot 147; avg 14.7; max 36. They were here from late November to early February.
  • lesser scaup: % days 31; tot 547; avg 54.7; max 94. We had quite a flock of these. They were on Lake #22 for quite a while, then spread to Lakes 24-29 for their last couple of weeks. They were here from the new year to early March.
  • ring-necked duck: % days 6; tot 14; avg 7.0; max 10. 10 in early December, 4 in late January???
  • double-crested cormorant: % days 91; tot 140; avg 4.8; max 12. No sign of a Cormorant Menace, yay!
  • anhinga: % days 81; tot 93; avg 3.6; max 10.
  • brown pelican: % days 41; tot 28; avg 2.2; max 4.
  • belted kingfisher: % days 31; tot 10; avg 1.0; max 1. Their distinctive chitter is easy to recognize.

Waders

Wader numbers seem to be down in general. 1 theory I have is that the lakes have been so full. I think the waders prefer things more marshy.
  • great egret: % days 97; tot 77; avg 2.5; max 4. No longer our most numerous wader.
  • great blue heron: % days 41; tot 19; avg 1.5; max 2. Down from last season.
  • snowy egret: % days 59; tot 54; avg 2.5; max 7. Down from last season. I last counted a snowy egret on 3/12.
  • cattle egret: % days 0.
  • tricolored heron: % days 91; tot 82; avg 2.8; max 7. Down from last season, but our most numerous wader this season.
  • little blue heron: % days 88; tot 79; avg 2.8; max 11. Down slightly from last season.
  • green heron: % days 16; tot 5; avg 1.0; max 1.
  • wood stork: % days 6; tot 2; avg 1.0; max 1.
  • white ibis: % days 97; tot 423; avg 13.6; max 41.
  • glossy ibis: % days 72; tot 210; avg 9.1; max 44.
  • limpkin: % days 22; tot 8; avg 1.1; max 2. Considerably fewer than last season.

Beach Birds

Raptors

Corvids

  • fish crow: % days 81; tot 632; avg 24.3; max 76. I am increasingly thinking it is pointless to count crows. The proper caw goes out, 100 crows can gather in 30 seconds or so. Similarly, the vultures will show up in large numbers depending on the size of the fish kill. I created a formula column in the spreadsheet, = # birds - fish crows - black vultures - turkey vultures, I may play with that some.
  • blue jay: % days 94; tot 376; avg 12.5; max 30.

Perching Birds (Passerines)
