I recently returned from a trip down to southern Brazil with my targets being five species of warblers that would be new to me including Southern Yellowthroat, White striped Warbler, Flavescent Warbler, white browed Warbler and Riverbank Warbler.  I was lucky enough to get all my targets and the story of them follows.  After a flight to Miami on the 6th and then a long flight to São Paulo I arrived on the 7th and stayed near the airport.

The first full day of the trip started off with me meeting up with my guide, Felipe, at the airport hotel around six in the morning. We then made the long drive to the southeast to Intervales State Park. The trip took about an hour longer than expected due to the horrible traffic in the sprawling city of São Paulo. We finally made it to the entry road into the park late in the morning, where we birded along the roadside during multiple stops. The first warbler of the trip was a group of Golden crowned Warblers that were very vocal in an area of dense brush along the road. The group featured both subspecies including at least one and possibly two of the white bellied subspecies that should be found further north. The guide had not seen the subspecies in the area before and was surprised to see one in the area. I got a decent amount of photos of the birds as well as a recording before we moved further along the road. A stop a short time later resulted in the first target of the trip being found with a Southern Yellowthroat singing constantly at the edge of a small marsh.  The yellowthroat showed quite well and became the last yellowthroat species I had yet to see (at least until more splits come along in the future). The next target we tried for was White browed Warbler. At this point we had arrived at Intervales SP and met up with a local guide. It was drizzling on and off as we started a walk down a trail near the park entrance in search of the warbler. We managed to turn it up fairly quickly and had great looks at the species as a male moved around us singing quite a bit. White browed Warbler has a range that includes southeast Brazil, Uruguay, northeast Argentina and a small portion of Paraguay. After snagging the second target in a short time we now had just one more possible new warbler species in the area, Riverbank Warbler. We tried for it at multiple spots without any luck until we were walking back out and had it singing in a spot we tried to find it earlier. Yet again the species turned out to be quite accommodating for photos with a little patience. We had now found three out of the five targets for the trip in the first day…not a bad start to the trip at all.  With the three targets found for the area in the first day we could broaden out to search for other non warbler species on the following day and a half. 

The second day of the trip was spent in and around Intervales State Park and after finding all three possible target warblers the day before we spent the day concentrating mainly on other species. The weather was not great with drizzle to some light rain all day long. Warblers were few and far between but loads of other life birds made up for the lack of warblers.

The third day of the trip found us spending the morning at Intervales SP again and with no target warblers to search for we spent our time tracking down other species. We did have warblers along the way including Golden crowned Warbler, White browed Warbler and the most Tropical Parula we had for the trip. The afternoon was spent mainly making the long drive to the Dourado area to the north of Intervales SP.

We started our full day in the Dourado area heading out early once again with the focus being the two remaining target species for the trip, White striped Warbler and Flavescent Warbler. The more difficult to find species in the area would be the White striped Warbler so that I was the species we focused on first. The species is a Brazilian endemic and is more likely to be found further north but we knew it was certainly possible with a little luck and local knowledge. We once again had a local guide with us which helped increase our chances of finding our targets. The first spot we tried failed to turn up the warbler but we did have lots of other good birds to take away the sting of not finding the warbler. Our next stop was much more productive and we heard the warbler calling and eventually it showed itself well and allowed me to get some decent photos as it worked through some dense edge habitat. With the toughest target now in hand we could relax a bit and bird some other areas before trying for the last target. After a few stops elsewhere we stopped along the Rio Jacare and could hear the warbler singing as we pulled up. The warbler eventually flew across to our side of the small river and after a bit of effort I was able to get some photos of yet another hyperactivity warbler species. Flavescent Warbler has a disjointed distribution with the species occurring in the southern half of Brazil into Bolivian and Paraguay and two other separated populations with one in northwest Venezuela and the other in Guyana. We also got some great looks at the white bellied subspecies of Golden crowned Warbler as we walked along the river.

On my last full day in Brazil we continued our search for new life birds for me and actually failed to find a single species of warbler for our efforts. Nonetheless we found lots of other good stuff so no warblers was okay for a day. 

As mentioned above the trip was productive with all five target warbler species seen well, photographed and a few recorded. Overall for the trip I had seven species of warbler including Southern Yellowthroat, Tropical Parula, Golden crowned Warbler (both yellow bellied and white bellied subspecies), White striped Warbler, Flavescent Warbler, White browed Warbler and Riverbank Warbler (southern subspecies). The second part of the trip then began with a red eye flight from Brazil to Panama.  More on the entire trip, including lots of stuff beyond warblers at the following link: Brazil Dec 2023.
