********
   Spring and early summer is a great time in Sicily Island Hills. During this period in 2021, I visited Sicily Island Hills on the following dates: March 4, 22; April 9, 18 (two observers); May 18 (two separate visits on 5/18, one to south part of WMA, and one to north part of WMA), and June 11. Here are some habitat shots before continuing:

Sweetleaf - 6/11/21 - This is the host plant for King's Hairstreak butterflies. There's a good amount of Sweetleaf growing around Rack Falls Trail/Rock Creek. I looked for the hairstreaks there during their mid-May to mid-June flight season (specifically on June 11), but found none.

   I've often thought that the forests of Sicily Island Hills look like excellent habitat for White-breasted Nuthatch, but it wasn't until this spring that I encountered the species there. The first was a heard-only  at a point on the main road in the south part of the WMA, toward the NW part of that road, on 4/9. I heard and saw the species on one more occasion, near the self-clearing kiosk in the southern part of the WMA on May 18. 
   Red-breasted Nuthatches wintered in SIH during 2020-2021. They showed up in the fall, and continued well into the dates covered in this post, with observations on March 4 (two individuals), March 22 (one), and  April 9 (one). All R-B Nuthatch observations were in the southern part of the WMA.

   During breeding season, Sicily Island Hills seems to host the greatest density of Worm-eating Warblers of any place that I bird. On March 22 I saw my FOS Worm-eating Warbler of 2021 by the south check-in kiosk in SIH.

   On April 18 we saw a Black Bear on the next side road on the left after the self-clearing kiosk in the southern part of the WMA. This is just across the hollow from the primitive campground. This was actually my first ever sighting of a wild Black Bear!

   On April 18 we tallied at least 56 Monarch caterpillars on Green Antelopehorn milkweeds growing along the main road in the south part of the WMA, near that road's northwest end.

   The butterfly highlight of SIH so far this year was seeing my lifer Mourning Cloak. This species has been reported from Sicily Island Hills in past years by other observers. The one I saw was in the road, just north of the WMA headquarters, which is in the north part of the WMA.

   Each year I try to make it to SIH to see the June flight of Yehl Skippers. This is the only location that I've personally seen this species (though they are found elsewhere in Cenla). They can be pretty common in SIH.

   May 18 was a good day for spring migrant birds. In the vicinity of the primitive campground and check-in kiosk, I found Blackburnian Warbler, Bay-breasted Warbler, and a couple of Magnolia Warblers, all males. The Magnolia and Bay-breasted were actually new species for my Sicily Island Hills bird checklist.

   Spring wildflowers are always impressive in SIH. Indian Pink, one of my favorite wildflowers, are abundant in SIH, with the largest number in bloom during April-May. Milkvine are fairly common here, and are often found in the same places as Indian Pink, blooming during the same timeframe.
